We are basing the Vista version of our product on Firebird, and can easily backup data from older XP version based on Interbase and restore them into firebird. However we have a need for backwards compatibility, ie to move data back from our Vista (Firebird) version to our XP (Interbase version). So far all attempts to backup from Firebird and restore under Interbase (7.1) have failed. Has anybody achieved this?
