History Sync

Drop migration history rows whose files no longer exist.

Syntax

$ vela migrate history-sync

The database records which migrations it has applied. If a migration file is deleted — a branch switch, a rebase, a squashed set of migrations — the record is left pointing at a file that isn’t there. This removes those rows so the history matches what is on disk.

It only touches the history table; it does not undo anything a deleted migration did to the schema. Run vela migrate up afterwards if the sync surfaces migrations that now count as pending.
