Power Platform Governance During Microsoft Migrations
Legacy forms and workflows often become visible during Microsoft 365 and SharePoint migrations. If those dependencies are rebuilt quickly without governance, the organization can replace one legacy problem with another.
Power Platform governance is not a blocker to modernization. It is what makes modernization supportable.
Governance decisions to make early
Define these decisions before large rebuild work begins:
- Environment strategy for development, testing, and production
- DLP policies and connector boundaries
- Ownership model for apps, flows, connections, and service accounts
- ALM expectations for solutions, variables, connection references, and deployments
- Monitoring, alerting, failure handling, and runbook ownership
- Backup, export, and documentation expectations
- Naming, tagging, and business-criticality standards
Migration-specific risks
Common risks include:
- InfoPath forms that depend on outdated data connections
- Nintex workflows tied to lists that are moving to SharePoint Online
- SharePoint Designer workflows that no one owns
- Power Automate flows created by individual users without support coverage
- Premium connectors that create unexpected licensing needs
- Apps and flows without deployment discipline
- Service accounts or credentials that break during tenant changes
Create a rationalization model
For each legacy form or workflow, decide whether to retire, replace, rebuild, redesign, or defer. This prevents the Power Platform backlog from becoming a one-for-one rebuild of old technical debt.
Use product accelerators when they fit
Horton Scientific uses Form Migrator to accelerate InfoPath discovery and rationalization, and Flow Migrator to accelerate Nintex and workflow migration planning. These tools help turn messy portfolios into prioritized modernization backlogs.
Build the operating model
Governance must survive after the migration team leaves. Define:
- Who can create apps and flows
- Which environments are approved for production workloads
- How critical flows are monitored
- How ownership changes are handled
- How failed runs are escalated
- How makers request new connectors
- How support teams triage issues
