  Description copied from interface: `Migration`
  All database migrations are run in the same transaction so if one fails, they will all be rollbacked. There are two ways to fail: either return false or throw an exception. The difference is that throwing an exception will stop the server startup whereas returning false will let the server continue its starting cycle and run on the non-migrated data.

  Specified by:
    `migrate` in interface `Migration`
