I noticed that, when upgrading to 2.53, it is highly advisable to restore db’s that were on 2.5.1, as stated in the docs :

Warning re Databases Created or Restored under Firebird 2.5.1

All users upgrading from Firebird 2.5.1 to a higher sub-release are strongly advised to migrate databases using gbak backup/restore. If this is impracticable, at least rebuild all compound indices in the databases being migrated.

Databases being upgraded from older Firebird versions (ODS 11.1 and lower) or v.2.5.0 are not affected by this regression.

My question is, do I need to perform the gbak on 2.5.1, then the restore on 2.5.3 ? Or is it ok if I simply gbak/restore on 2.5.3
