Planning reversal during an Airtable migration
I keep Airtable authoritative until the agreed checks pass and document when reversal stops being straightforward. New writes made only in the replacement require a reverse export or another recovery plan. I rehearse that path with a scratch base.

How do I plan reversal during an Airtable migration?
I keep Airtable authoritative until the agreed checks pass and document when reversal stops being straightforward. New writes made only in the replacement require a reverse export or another recovery plan.
Method
- Keep Airtable authoritative and the new system read-only until reconciliation passes.
- During the dual-write phase, write to Airtable first and mirror to the new system; test how failures affect each copy.
- Record the point of no return explicitly: the first write that exists only in the new system.
- For the post-cutover window, maintain a reverse export that can repopulate the base.
- Set a retention date for the read-only base and put it in the handoff document.
What can go wrong
- Dual write in the wrong direction, which silently makes the new system authoritative early.
- Without a reverse export, restoring new records to Airtable can require manual work.
Checks to try
- Run the reverse export into a scratch base and reconcile it.
- The point of no return is documented and dated.
