Firebird will fine but if doing this i do suggest firebird 2.5 problems: 0) be aware you can't go back, 1) watch out for UDF changes 2) test on a VM like "Oracle VM VirtualBox" first 3) read about the Meta_data tag in the Documentation for restoring the database. i do suggest using classic server as well as its better suited to multi processor boxes.
