Firebird and InterBase have had six years of independent development
with programmers who have different goals. The Firebird developers
are more rigorous about detecting potential errors.

That's the right procedure, generally, but I would start by using ISQL
to extract the system metadata from the database - using InterBase's
ISQL. Then I'd drop all the procedures using InterBase's ISQL again.
Then I'd use Firebird's backup/restore to create a Firebird database.
If that works, I'd try recreating the procedures from the extracted ddl
