Loop / Loop until / Do until

What it does

This control action changes workflow execution flow. It determines whether actions run, how collections are processed, or which branch or stage is active at runtime.

How Flow Migrator maps it

Flow Migrator maps this to Do until using Control. Maps loop conditions to Do until where the source condition can be parsed. Flow Migrator has a direct or proven best-effort conversion path for this mapping.

Common migration issues

• Check converted expressions, branch ordering, loop exit conditions, and state-machine transitions.
• Run a test instance and compare outputs against the original Nintex workflow before production migration.

Validation checklist

1. Open the generated flow and confirm the action card imported correctly.
2. Validate connection references and required settings before running the flow.
3. Test with representative source data from the original workflow.
