Power Automate workflow modernization replaces unsupported or difficult-to-maintain SharePoint workflows, InfoPath forms, email approvals, spreadsheets, and custom automation with governed Microsoft Power Platform solutions.
The goal is not to recreate every legacy process exactly as it works today. Modernization should simplify unnecessary steps, improve the user experience, strengthen security and auditability, reduce operational risk, and create automation that can be supported across development, testing, and production environments.
This has become urgent for organizations that still depend on SharePoint Designer and InfoPath. SharePoint 2013 workflows in Microsoft 365 were fully retired on April 2, 2026. InfoPath 2013 reached the end of extended support on July 14, 2026. SharePoint Server 2016 and SharePoint Server 2019 also reached extended end of support on July 14, 2026.

What Is Power Automate Workflow Modernization?
Workflow modernization is a structured business and technology program that transforms outdated process automation into secure, maintainable, scalable, and measurable solutions.
Legacy environments commonly include:
- SharePoint Designer 2010 and 2013 workflows
- InfoPath forms and form libraries
- SharePoint Server workflow applications
- Custom event receivers, timer jobs, and farm solutions
- Email-based approvals
- Excel trackers and manual status updates
- Third-party workflow engines
- Custom scripts connected to SharePoint lists
- Processes understood by only one employee or vendor
Modern solutions may use Power Automate for orchestration, Power Apps for user interaction, SharePoint or Dataverse for data, Teams for approvals and notifications, Power BI for reporting, and approved connectors for enterprise systems. Teams unfamiliar with the cloud platform can review what SharePoint Online is and its key collaboration and content features.
Organizations modernizing SharePoint should treat content and process transformation together. The SharePoint migration services guide explains why moving documents without addressing workflows, permissions, applications, and governance creates incomplete modernization.
Why Legacy SharePoint Workflows Must Be Modernized
Platform retirement and support risk
SharePoint 2013 workflows were retired from SharePoint Online in April 2026. InfoPath 2013 is now out of support. Organizations still relying on these technologies face reliability, security, compatibility, vendor-support, and business-continuity concerns.
Hidden business dependence
Legacy workflows frequently support employee onboarding, procurement, policy approval, contracts, compliance reviews, incident reporting, leave requests, customer onboarding, equipment requests, and financial controls. A workflow failure may stop an operational process even when the SharePoint site itself remains available.
Maintenance concentration
Many older solutions are understood by only one developer, administrator, or external partner. Missing documentation, hard-coded accounts, unsupported connectors, direct permissions, and custom scripts increase operational risk.
Poor user experience
Legacy forms and workflows may not support mobile devices, Teams-based work, modern accessibility, real-time status, self-service, or clear error messages.
Limited integration
Modern processes often need Microsoft Teams, Outlook, Dynamics 365, ERP systems, service platforms, Dataverse, APIs, and cloud applications. Older workflow platforms were not designed for this connected environment.
Governance and audit limitations
Unmanaged flows can create duplicate automation, uncontrolled connectors, uncertain ownership, credential risks, weak monitoring, and incomplete audit evidence. Modernization provides an opportunity to establish a repeatable operating model.
Organizations on unsupported SharePoint versions should also review the SharePoint end-of-support guide.
Legacy Workflow Technologies and Their Current Status
| Technology | Current Modernization Position |
|---|---|
| SharePoint 2010 workflows in SharePoint Online | Retired earlier and should no longer be treated as a supported cloud workflow option |
| SharePoint 2013 workflows in Microsoft 365 | Fully retired from existing tenants on April 2, 2026 |
| SharePoint Designer 2013 | Legacy design tool; not a strategic foundation for new automation |
| InfoPath 2013 | Extended support ended July 14, 2026 |
| SharePoint Server 2016 and 2019 | Extended support ended July 14, 2026 |
| Power Automate | Microsoft’s cloud workflow automation platform within Power Platform |
| Power Apps | Modern low-code option for forms and business applications |
| Microsoft Forms | Suitable for surveys, feedback, and simpler data-collection scenarios |
| Dataverse | Structured business data platform for more complex and relational applications |
Technology status alone does not determine the replacement. Each workflow should be evaluated according to business value, data, complexity, volume, security, compliance, user experience, integration, and support requirements. This connects workflow decisions with the broader business benefits of SharePoint.
Workflow Discovery and Assessment
A modernization program should begin with discovery rather than development. Organizations are often surprised by the number of workflows, forms, scripts, integrations, and manual workarounds operating across SharePoint.
Build a workflow inventory
| Inventory Field | Purpose |
|---|---|
| Workflow and process name | Identifies the business capability |
| Business owner | Assigns accountability for requirements and approval |
| Technical owner | Identifies support and platform responsibility |
| Technology | SharePoint Designer, InfoPath, custom code, third party, email, or Power Platform |
| Trigger and frequency | Shows execution volume and timing |
| Users and departments | Measures impact and change scope |
| Data sources | Identifies SharePoint, SQL, ERP, CRM, email, files, and APIs |
| Approvals and exceptions | Documents decision points and non-standard paths |
| Security and compliance | Captures sensitivity, retention, audit, and access requirements |
| Failure impact | Determines operational and financial risk |
| Modernization decision | Retire, replace, modernize, consolidate, or re-engineer |
Use usage evidence
Do not assume a workflow is important because it exists. Review execution history, last-used dates, failure rates, user volume, help-desk incidents, approval delays, and business-owner confirmation.
Document current-state process maps
Capture triggers, actors, steps, decisions, integrations, delays, manual handoffs, escalation, records, and exceptions. This reveals process problems that technology alone will not solve.
Retire, Replace, Modernize, or Re-engineer
Retire
Remove workflows that no longer serve a business purpose, duplicate another process, support an obsolete policy, or have no active users.
Replace
Use standard Microsoft 365 or Power Automate capability for simple notifications, reminders, approvals, list updates, or document review processes.
Modernize
Redesign valuable business processes using Power Apps, Power Automate, SharePoint, Teams, and reporting. Modernization should simplify steps and improve visibility rather than reproduce old logic exactly.
Consolidate
Combine multiple departmental workflows that perform the same function with different names or minor variations. A configurable enterprise process is often easier to govern than many copies.
Re-engineer
Complex, high-volume, regulated, or multi-system processes may need Dataverse, Azure services, custom APIs, integration middleware, or a purpose-built application rather than a simple cloud flow.
Business value and risk should determine priority. High-volume, compliance-related, customer-facing, financially significant, or business-critical processes should generally be assessed first.
Designing the Future-State Process
The most common modernization mistake is rebuilding a bad process. Before selecting connectors or creating a flow, challenge the existing design.
Questions to ask
- Why does this process exist?
- Which policy or control requires each approval?
- Can approvals be combined or delegated?
- Can data be captured once rather than re-entered?
- Can validation occur automatically?
- Can users see status without emailing an administrator?
- What happens when an approver is absent?
- Which exceptions require human judgment?
- What evidence must be retained?
- Can the process be standardized across departments?
Design for the user
Forms should be clear, accessible, mobile-friendly, and appropriate to the task. Users should understand required fields, approval status, next steps, errors, and expected completion time.
Design for operations
Administrators need run history, failure alerts, support ownership, retry procedures, dashboards, dependency documentation, and controlled deployment. A workflow is not production-ready simply because it worked once in a maker’s account.
Modern Power Platform Architecture
A modern solution can combine several services:
| Component | Role |
|---|---|
| Power Apps | User interface, data entry, validation, and role-based business application experience |
| Power Automate | Workflow orchestration, approvals, notifications, integration, and scheduled processing |
| SharePoint | Documents, lists, metadata, collaboration, and content management |
| Dataverse | Relational business data, security roles, business rules, and solution lifecycle |
| Microsoft Teams | Approvals, notifications, adaptive cards, and collaboration |
| Power BI | Operational reporting, trends, bottlenecks, and management dashboards |
| Copilot Studio | Conversational experiences and governed agents |
| Azure and APIs | Advanced integration, custom services, and enterprise-scale processing |
Use SharePoint when
The process is document-centric, collaboration-focused, relatively straightforward, and can operate effectively with SharePoint lists, libraries, permissions, metadata, and Microsoft 365 integration.
Use Dataverse when
The solution requires complex relational data, stronger application security, multiple business applications, advanced lifecycle management, or enterprise-scale data operations.
Use standard connectors carefully
Connector availability does not automatically mean a connector is approved. Security, data movement, licensing, ownership, and Data Loss Prevention policies should determine what can be used.
Organizations integrating SharePoint with CRM can review the guide to SharePoint and Dynamics 365 integration.
InfoPath Modernization and Form Replacement
InfoPath forms should be assessed independently from workflow logic. A single InfoPath solution may include field validation, conditional sections, repeating data, code-behind, external data connections, digital signatures, print layouts, and complex business rules.
Power Apps
Power Apps is a common replacement for interactive business forms and applications. It supports responsive layouts, mobile experiences, role-based logic, connectors, and integration with Power Automate.
Microsoft Forms
Microsoft Forms may suit surveys, feedback, registrations, and simple request intake where complex data relationships or application behaviour are not required.
SharePoint modern forms
Standard list and library forms may be sufficient for basic data capture and document metadata. Avoid introducing a custom application when the standard experience meets the need.
Custom applications
Complex offline requirements, advanced signatures, highly specialized interfaces, or demanding integration patterns may require custom development or Azure services.
Form selection should follow future-state requirements—not a one-to-one attempt to imitate InfoPath. Complex solutions may also require the engineering practices described in the guides to secure SharePoint development and enterprise SharePoint development.
Power Automate Governance Best Practices
Low-code development can accelerate delivery, but unmanaged growth creates duplicate flows, unknown owners, personal connections, security concerns, and support problems.
Environment strategy
Separate development, testing, and production. Use environment groups or managed environments where appropriate to apply consistent governance. Restrict who can create new environments and define when dedicated environments are required.
Solutions
Production applications and flows should be solution-aware where practical. Solutions support controlled packaging, dependencies, connection references, environment variables, deployment, versioning, and application lifecycle management.
Data Loss Prevention policies
DLP policies should classify connectors into appropriate business, non-business, or blocked groups. Policies should reflect information risk and prevent unsafe data movement between approved business services and unapproved consumer services.
Ownership and service continuity
Every flow should have a business owner and technical support owner. Production processes should not depend entirely on one employee’s personal account or undocumented connection.
Naming and documentation
Standard names should identify department, process, purpose, environment, and version. Documentation should include trigger, actions, data, owners, dependencies, permissions, exception handling, support steps, and retirement criteria.
Center of Excellence
A Power Platform Center of Excellence can define standards, enable makers, monitor inventory, provide templates, review risk, support deployment, and promote reusable components. A CoE should enable responsible innovation rather than becoming only an approval bottleneck.
Security, Identity, and Compliance
Least privilege
Flows, connections, applications, service principals, and users should receive only the permissions required. Broad SharePoint access or high-privilege credentials should not be used simply to make a workflow work.
Connection governance
Review connector credentials, account ownership, expiration, consent, shared connections, and offboarding impact. Use appropriate service identities or service principals where supported and justified.
Secrets and configuration
Do not hard-code passwords, endpoints, identifiers, or environment-specific settings inside flows. Use approved secret management, connection references, and environment variables.
Audit and evidence
Compliance workflows should preserve approval decisions, timestamps, actors, version information, exceptions, and required records. Retention and audit design should be validated with Legal, Compliance, and Records teams.
Microsoft Purview
Purview can support sensitivity labels, DLP, retention, records management, audit, eDiscovery, and compliance controls across Microsoft 365. Automation should reinforce these controls rather than bypass them.
Application Lifecycle Management
Production workflow modernization should follow controlled application lifecycle management rather than direct editing in production.
Recommended lifecycle
- Capture approved business requirements.
- Design the future-state process and architecture.
- Build in a development environment.
- Use solutions, environment variables, and connection references.
- Perform functional, security, integration, performance, and accessibility testing.
- Complete user acceptance testing.
- Deploy through an approved release process.
- Validate production connections and permissions.
- Monitor performance and failures.
- Optimize, version, and eventually retire the solution.
Testing scenarios
- Normal and exception paths
- Missing or invalid data
- Approver absence and delegation
- Permission failures
- Connector and API outages
- Duplicate submissions
- Timeouts and retry behaviour
- High-volume execution
- Retention and audit evidence
- Rollback and recovery
Monitoring, Support, and Operational Management
Every business-critical flow should have defined monitoring and support.
Monitor
- Run success and failure rates
- Execution time and throttling
- Approval delays
- Connector errors
- Expiring credentials and connections
- Capacity and licensing usage
- Abandoned or ownerless flows
- User adoption and support incidents
Error handling
Flows should detect failures, capture useful diagnostic information, notify the correct support team, avoid duplicate transactions, and provide a recovery or reprocessing path.
Support tiers
Define whether support belongs to a departmental maker, central automation team, application support, managed service provider, or enterprise service desk. Business-critical automations require escalation and continuity beyond the original developer.
Operational reporting can be strengthened through the analytics patterns described in the guide to Microsoft Power BI and Fabric.
Workflow Modernization During SharePoint Migration
Workflow discovery should occur early in a SharePoint migration. Content and workflows are connected through lists, libraries, fields, permissions, content types, users, and integrations. Migrating content first can break process dependencies or force rushed rebuilding later.
Recommended migration sequence
- Inventory sites, forms, workflows, scripts, and integrations.
- Identify unsupported and business-critical dependencies.
- Assign business owners and confirm actual usage.
- Classify workflows as retire, replace, modernize, consolidate, or re-engineer.
- Design target SharePoint architecture and data models.
- Build and test modern solutions before the associated cutover.
- Migrate content and configuration in coordinated waves.
- Validate workflow triggers, permissions, connections, and business continuity.
- Train users and provide stabilization support.
Organizations moving to Microsoft 365 can review the guidance for SharePoint Online implementation, the comparison of SharePoint Online and on-premises SharePoint, and the complete Microsoft 365 consulting guide.
AI, Copilot, and Intelligent Automation
Power Automate, AI Builder, Copilot, and Copilot Studio can support document extraction, classification, summarization, natural-language assistance, workflow creation, decision support, and conversational process experiences.
AI should not be added to a weak process simply because the capability exists. Successful AI-enabled automation depends on:
- Approved use cases
- Trustworthy data and content
- Accurate permissions
- Clear human validation
- Privacy and compliance controls
- Prompt and output governance
- Monitoring, audit, and incident response
- Measurable business outcomes
Human approval should remain where legal, financial, safety, ethical, or high-impact decisions require judgment. AI-generated content should be verified before it becomes an official record or triggers a critical action.
Review the introduction to Microsoft Copilot and the guide to Copilot for Microsoft Teams.
Power Automate Workflow Modernization Roadmap
Phase 1: Discover
Inventory workflows, forms, customizations, data, integrations, owners, usage, risk, failures, and platform status.
Phase 2: Prioritize
Rank processes according to business impact, compliance, volume, failure risk, user experience, technical complexity, and modernization value.
Phase 3: Redesign
Simplify approvals, eliminate manual handoffs, standardize variants, improve data capture, and define future-state ownership.
Phase 4: Establish governance
Define environments, DLP, connector policies, naming, ownership, solutions, ALM, security, support, and monitoring.
Phase 5: Build and test
Develop the solution in controlled environments and complete technical, security, compliance, integration, and user testing.
Phase 6: Deploy in waves
Start with high-value or high-risk workflows, then scale through repeatable patterns. Avoid attempting to rebuild every workflow simultaneously.
Phase 7: Adopt and optimize
Train users, monitor outcomes, resolve bottlenecks, improve the process, and retire the legacy technology after validated cutover.
Change management principles from the guide to successful SharePoint adoption apply equally to workflow modernization.

Frequently Asked Questions
What is Power Automate workflow modernization?
It is the assessment, redesign, rebuilding, governance, deployment, and optimization of legacy workflows using Power Automate and related Microsoft Power Platform services.
Are SharePoint 2013 workflows still available in SharePoint Online?
No. SharePoint 2013 workflows were fully retired from existing Microsoft 365 tenants on April 2, 2026.
Is InfoPath 2013 still supported?
No. InfoPath 2013 reached the end of extended support on July 14, 2026.
Can SharePoint Designer workflows be converted directly to Power Automate?
There is generally no reliable one-click conversion for complete business processes. Most workflows require assessment, redesign, rebuilding, testing, and business validation.
What replaces InfoPath?
Replacement options include standard SharePoint forms, Power Apps, Microsoft Forms, Dataverse-based applications, or custom solutions depending on complexity and requirements.
Should every legacy workflow be rebuilt?
No. Some workflows should be retired, consolidated, or replaced with standard Microsoft 365 capability. Only processes with continuing business value should move forward.
When should Dataverse be used instead of SharePoint lists?
Dataverse is often appropriate for complex relational data, enterprise applications, advanced role-based security, multiple connected applications, and stronger solution lifecycle requirements.
What governance controls are essential?
Core controls include environment strategy, DLP, approved connectors, solution-aware development, connection references, environment variables, ownership, naming, security, monitoring, and lifecycle management.
Can Power Automate integrate with third-party systems?
Yes. Power Automate supports many connectors and API integration patterns, but each connection should be evaluated for licensing, security, data movement, reliability, and support.
How long does workflow modernization take?
A simple workflow may take weeks, while an enterprise portfolio with forms, integrations, governance, migration, and multiple departments may require a phased program over several months.
Should workflow modernization happen before SharePoint migration?
Workflow assessment should happen early. Rebuilding and migration can then be coordinated so content structures, permissions, forms, triggers, and business cutover remain aligned.
How does Power Automate support AI readiness?
Modern governed workflows create structured processes and reliable data that can support AI Builder, Copilot, agents, intelligent document processing, and future automation use cases.
