While connecting to a bak file using firebird on 64 bit Ubuntu system I am getting error as file is invalid. But may be it is because of bit issue of the system. Because I have connected the same database on my Ubuntu 32 bit system. So here what should I do? Is there any way to convert a 64 bit file on 32 bit machine.

  • It's not clear from your question what you want to do. Please read http://stackoverflow.com/help/mcve and ask again - possibly on http://serverfault.com/ – Vorsprung Apr 27 '16 at 07:59

  • As I already said on the other question: you need to create a real backup with gbak and restore that. You currently don't have a backup, just a copy of a Firebird database file (likely Firebird 1.5 or earlier, because afaik Firebird 2.0 (or maybe 2.1) no longer has a different structure for 32 bit and 64 bit). – Mark Rotteveel Apr 27 '16 at 14:53

Create a backup on the 32-bit system using gbak -b -t (for transportable) and restore on the 64-bit system.
