All - we have a FB1.5 db Dialect 1 running on W2003. Size is about 10GB.

I assume this db will run as-is under FB2.5 - the big question is backing up and restoring (and other tools like gfix) - given it is dialect 1 (it started out as an IB5.5!) will GBAK in FB2.5 respect and retain the dialect 1. I know it should be upgraded to dialect 3 but there are so many date issues we simply do not have enough time to pump into another db as it is in use nearly 24x7

Regards

Roger
