Part 1: Why Power Apps Is the Right InfoPath Replacement for Your Organization
Part 2: How to Migrate InfoPath Forms to Power Apps — The Technical Breakdown
Part 3 (this post): Building Your InfoPath to Power Apps Migration Plan — Timeline, Cost, and Checklist
From Technical Knowledge to an Executable Migration Plan
Parts 1 and 2 of this series established why Power Apps is the right InfoPath replacement and walked through every technical mapping, data migration step, and workflow rebuild pattern your development team needs. This final post is about execution — building the project plan, setting realistic expectations with leadership, and having a checklist that keeps your migration on track through to go-live.
The organizations that successfully migrate InfoPath portfolios before the July 14, 2026 deadline do not just have good developers. They have a structured plan, honest budget conversations, and a clear owner for every workstream. This post gives you the framework for all three.
Want an expert-built migration plan for your specific InfoPath environment?
WME delivers assessment-led, fixed-scope InfoPath to Power Apps migration engagements.
Step 1: Complete Your Form Inventory and Classification
No migration plan is credible without a verified inventory. Use the Microsoft 365 Assessment Tool (PnP project at github.com/pnp/pnpassessment) to scan your tenant and produce a complete InfoPath form inventory — including location, usage frequency, form type, and content type associations.
Once you have the inventory, classify every form into three categories before writing a single line of Power Fx:
Classification | Definition | Target % |
Retire | Form is inactive, process has ended, or data is historical with no active business need | 20 to 40% of most portfolios — reduces rebuild scope significantly |
Archive | Form is inactive but data requires compliance lookback preservation | Variable — depends on regulatory retention requirements |
Rebuild in Power Apps | Form supports an active business process and must be migrated to Power Apps | Remaining forms after retire/archive classification |
THE MOST VALUABLE HOUR IN YOUR MIGRATION PROJECT
Quisitive and other Microsoft Partners consistently find that 20 to 40% of legacy InfoPath forms can be retired after a proper stakeholder review.
That retirement decision — made before development starts — is the single highest-leverage action in your migration project. It can reduce your rebuild queue by a third before a developer touches Power Apps Studio.
Step 2: Define Your Migration Phases and Prioritization
With a classified inventory in hand, sequence your rebuild queue into three phases based on business criticality and technical complexity:
Phase | What Goes Here | Why This Sequence |
Phase 1 — Quick wins | High-criticality, low-complexity forms. Simple data capture with no premium connectors and minimal workflow logic. | Reduces the highest operational risk first. Builds team confidence and validates your Power Apps approach before tackling harder forms. |
Phase 2 — Core portfolio | Medium-complexity forms with conditional logic, SharePoint list connections, and Power Automate approval workflows. | The bulk of most InfoPath portfolios. Execute after Phase 1 validates your methodology. |
Phase 3 — Complex forms | Low-criticality but technically complex forms — SOAP connections, Dataverse relational data models, custom SPFx scenarios. | Reserve for the final phase. These forms take the most time but carry the lowest operational risk if they slip slightly. |
Step 3: Build Your Project Timeline
Use the following timeline benchmarks from Microsoft Gold Partner project data to set realistic expectations with leadership and project sponsors:
Portfolio Size | Estimated Active Project Time | Key Assumptions |
Under 10 simple forms, basic workflows | 2 to 4 weeks | Standard connectors only, flat data model, no complex repeating sections or compliance requirements |
10 to 50 forms, moderate complexity | 4 to 12 weeks | Mix of simple and complex forms, some Power Automate rebuilds, parallel testing cycles included |
50+ forms, 100+ workflows | 8 to 16 weeks | Full dependency mapping, phased rebuild, parallel testing, and user training across business units |
Enterprise — 100+ forms, regulated industry | 12 to 18 months end-to-end | Full discovery program, Dataverse architecture, compliance evidence documentation, organizational change management |
Compass365 partner engagement range | 4 to 28 weeks | Full discovery through rollout — varies by scope and organizational readiness |
INTERNAL PLANNING DEADLINE — NOT JULY 14
Your team’s internal target should be May 1, 2026 — two weeks before Microsoft’s May 18 publishing block makes all remaining InfoPath forms immovable.
Work backward from May 1. If your migration takes 8 to 12 weeks of active work, that means your assessment and planning phase should already be complete or underway right now.
Step 4: Staff Your Migration Correctly
A successful InfoPath to Power Apps migration requires both internal knowledge and external technical expertise. Here is how to divide the workload:
Keep Internal — Irreplaceable Context | Engage Externally — Specialist Skills |
Business rule documentation — only your team knows what the form should do | Power Fx canvas app development for complex logic and data binding |
Form owner identification across business units | Dataverse data modeling, schema design, and security configuration |
User acceptance testing and business sign-off | Power Automate flow development for approval routing and automation |
Change management, communication, and training delivery | XML data extraction, parsing, and historical submission migration scripting |
Go/no-go decisions on retire vs. rebuild classification | SPFx Form Customizer development for advanced SharePoint-native scenarios |
Executive reporting and stakeholder management | Power Apps Premium connector configuration and governance/DLP setup |
The InfoPath to Power Apps Migration Checklist
Use this checklist to track your migration project from initial assessment through final decommission. Print it, assign owners, and update it weekly.
Checklist Item | Owner / Status |
Run Microsoft 365 Assessment Tool — produce complete InfoPath inventory (classicinfopath.csv or Power BI report) |
|
For on-premises environments, run SMAT to produce infopath-detail.csv before October 2026 |
|
Identify business owner for every active InfoPath form |
|
Classify every form: Retire, Archive, or Rebuild — target 20 to 40% retirement |
|
Extract all workflow history BEFORE running SPMT — permanently dropped during migration |
|
Bulk-export all .xml form submissions from SharePoint Form Libraries via PowerShell |
|
Generate PDF/A archives of historical submissions for compliance lookback |
|
Determine Power Apps licensing posture — standard M365 vs. Premium for premium connectors |
|
Analyze each rebuild-queue form for repeating sections, SOAP connections, People Picker fields, and embedded attachments |
|
Define data architecture per form — SharePoint Lists vs. Dataverse |
|
Map InfoPath rules and data connections to Power Fx and Power Apps connectors |
|
Rebuild Phase 1 forms (high-criticality, low-complexity) — validate approach |
|
Rebuild Phase 2 forms (core portfolio) — parallel test against InfoPath where possible |
|
Rebuild Phase 3 forms (complex) — SPFx or Dataverse scenarios |
|
Rebuild all associated SharePoint Designer workflows in Power Automate |
|
Complete user acceptance testing for all rebuilt forms |
|
Deliver user training and change management communications |
|
Execute phased rollout by department — validate before full cutover |
|
Set internal go-live target: May 1, 2026 (two weeks before May 18 publishing block) |
|
Decommission InfoPath form associations from SharePoint libraries |
|
Archive all .xsn and .xml originals in compliant document library |
|
Document compliance evidence — confirm HIPAA, SOX, ISO 27001 audit trail is intact post-migration |
|
Update IT asset inventory to reflect decommissioned InfoPath infrastructure |
|
