Moving from CentOS to Ubuntu is not really an upgrade, and more a
migration, you might hit some snags that have nothing to do with Firebird.

I am assuming that you will be using the Firebird version of the
distribution, but as you haven't mentioned a specific version: if you
update to a higher 2.5.x version of Firebird there should be no
compatibility problems.

Yes, moving to the last 2.5 version available in Ubuntu.

If you upgrade to a 3.0.x version of Firebird there might be
compatibility issues and you will need to migrate the database using a
backup under Firebird 2.5 and restore under Firebird 3.0. Consult the
Firebird 3 release notes for details.

This is not the plan for now. 

And above all else: test the upgrade, especially when going to Firebird 3.

As to ProDoctor, I have never heard from it, you might want to consult
the vendor for information and compatibility.

Thanks, Mark!
