Given that IB7.5 and FB split at an earlier point in the chain, I would
not expect a backup from one to restore in the other. But you should be
able to take the DML from one and create an empty database in the other.
At which point you will find the features that are going to cause
problems. Once you have a working 'blank' then datapump should work
fine. I understand that some of the admin tools will allow you to
connect to both servers and do that, but I never moved beyond IB6 ;)
