Nintex to Power Automate migration is appearing on more project lists as organisations consolidate their Microsoft stack. The business case is often clear. The execution is consistently more complex than estimates suggest.
It is not a translation — it is a rebuild
The most dangerous assumption: Nintex workflows can be translated into Power Automate flows with minimal design work. They cannot. Different execution models, trigger mechanisms, action libraries, and approaches to variables and error handling. The migration requires rebuilding with Power Automate patterns.
The inventory problem
Before planning, know exactly what you have. For each workflow: is it active, who owns it, what business process does it support, what happens if it stops running?
Prioritisation
- Business criticality first
- Simple workflows early — build team confidence
- Unclear ownership last — harder to validate
- Unused workflows → retire rather than migrate
Feature parity gaps
Nintex's approval UI is richer than Power Automate's native approvals. Lazy approval works differently. Nintex reporting needs alternative implementation in Power BI.
Migration projects that try to achieve feature parity take longer and cost more than those that use the migration as an opportunity to simplify. Ask whether each Nintex feature is still needed, not just how to replicate it.
Realistic timeline: two to three weeks per complex workflow for design, build, test, and validation. Never assume a complex workflow migrates in a day.
