>>I'm evaluating the choice of migrating a 1.5 Firebird database either to 2.1 or to 2.5. I've readed the release notes of both versions but I can't find no elements that help to decide which one could be best choice.

Personally, I upgraded from 2.1 to 2.5.1 because of the new features I needed to take advantage of. I have ditched FreeUDFLib. I have also started using temporary tables to speed up certain complicated queries, that would otherwise have been too slow to implement.

>>I've tested the client application with both versions (2.1 and 2.5) and it seems to work fine. My questions are:

>>- Is there any good reason for not migrating to 2.5 and migrate to 2.1?

Personally, I would just use the latest version, but I have recently had a Debian customer point out that there isn't a stable 2.5.1 build for them yet.

>>- Should I jump directly to 2.5, keeping in mind that SQL and data contents migrating issues could be almost the same in both versions?

I recently changed from 2.1 to 2.5.1 and had no issues with anything needing to be changed on my side.

>>- Has somebody any application running Delphi BDE components using Firebird 2.5?

Sorry, I use Delphi XE2 and FIBPlus data access components.



Hope that helps somewhat!
