tests/resources/migrations/live-image-test.py IMAGE moves two accounts from a Dovecot with the image's own inbuxa-migrate, and restarts the server once the first is done. The run shows as interrupted, the secret is gone with the restart, and the move carries on with it given again: the first account "done earlier", the second to the end, every mailbox whole and nothing twice. Then the passwords, a final pass that brings a late message, and close. Docker and python3 only; it removes what it starts. seed.py takes --bulk N, a folder big enough for a run to be cut off.
