I guess you can imagine that you first need to do that before backing up
and restoring?

* What is the character set of your database used when you have created
the database in the past?
* What is the exact error message?
* How did you install Firebird 2.5?

Is there another way to migrate? With the scripts while

backup/restore via gbak is the preferred solution, because it also moves
data. Of course, you still can create an empty Firebird 2.5 based
database with a DDL script and then pump your data with a tool from
your source into the destination database.
