If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which data or workflow was hardest to move?
What information did you need before starting the move?
Which post-migration task still feels difficult?
Which old workflow has no obvious equivalent?
What should have been checked before moving data?

Author notes / illustrative keys where applicable:
1. Identify the difficult data or workflow category without collecting the actual data being moved.
2. Find information needed before the move, such as mapping rules or prerequisites, rather than only surveying the final result.
3. Keep post-migration usability problems visible after the transfer itself is complete.
4. Identify the purpose of a missing equivalent before assuming the old implementation should be copied exactly.
5. Find a pre-move check that could have revealed an issue without claiming the survey proves migration integrity.
