Nintex to Power Automate Migration Guide

1. Discover what is actually running

• Inventory workflows by site, list, library, item trigger, scheduled trigger, manual trigger, owner, last run, failure history, and business process.
• Document actions that update SharePoint data, send mail, create tasks, call external systems, generate documents, manage approvals, or drive compliance steps.
• Identify service accounts, credentials, connectors, API calls, web service actions, on-prem dependencies, and notification mailboxes.
• Capture the validation owner for each workflow. A workflow cannot be considered migrated until the process owner confirms outcomes.

2. Choose the right migration path

• Retire workflows that support obsolete processes, inactive sites, abandoned forms, or duplicate work.
• Rebuild simple workflows with standard Power Automate trigger/action patterns and clear owner handoff.
• Redesign complex processes when the old workflow depends on long-running state, custom code, fragile approvals, or unsupported connectors.
• Use Dataverse, Azure Functions, Logic Apps, or integration middleware when Power Automate alone is not the right architecture.
• Consolidate similar workflows into reusable patterns when departments built variations of the same process.

3. Set Power Automate production standards

• Use solutions, environment variables, connection references, service accounts, documented ownership, and consistent naming.
• Add error handling, alerts, retry logic, run logging, owner notifications, and support runbooks.
• Document DLP policy impact, connector risk, premium licensing needs, and environment boundaries.
• Test with representative data and process owners before disabling legacy workflows.

4. Use Flow Migrator for the workflow estate

Nintex migration should be a program, not a collection of emergency rebuilds. Flow Migrator is the product path for organizing workflow discovery, prioritization, and migration planning into Power Automate.

• Use Flow Migrator when there are many workflows, unknown owners, unclear dependencies, or a tight migration deadline.
• Pair the product with Horton Scientific consulting when workflows require process redesign, governance, Power Platform architecture, or integration planning.
• Use the guide outputs as input for Flow Migrator discovery, scoring, migration backlog, and cutover planning.
