TOO_NEW: database

planMigrations reports TOO_NEW when the database’s ledger is ahead of the code. Here the ledger records 4 applied migrations of theatre.app and the code has 3. Older code cannot tell what migration 4 changed, so nothing is run against the database.

Sequence (descriptions only)

  id: 'theatre.app',

Error

TOO_NEW
The migrations cannot be applied safely.
  TOO_NEW: theatre.app: the database is at 4, this code knows 3 — it was migrated by newer code.
