The originally released IB 6 would read an IB 5.x (ODS 9) database; then
Borland disabled that capability when they rebuilt their (then Open Source)
binaries in January 2001 after the security flare. I can't remember the
reason for disabling it. Firebird didn't follow suit.

Firebird can read and write to IB 5.x databases. It treats them as Dialect
1; and you won't be able to convert them via the Dialect 2 client route.

If you want to work permanently with your db as a Firebird database,
convert it to ODS 10 by
1. gbak-ing it in -transportable format using the IB 5.x version of gbak
2. restoring it using the Firebird version of gbak

ODS = On-disk structure (the way the db engine lays out the database file)
