Yes you can, but the best approach is create a backup with 2.x version then
restore in 2.5 to get the advantages of new ODS.

Assunto: [firebird-support] Moving from 2 to 2.5?





I would like to test the transition from 2.x to 2.5 on a backup machine we
have. Am I correct in believing I can simply move the data files over and
point the 2.5 server at them?

The only note I found on this was this:

Which appears to detail problems in one particular file. But I can't tell
from context if this is a general issue or applies only to the USERs.
