No, you have to use different versions of gbak to revert a database from
a newer ODS to an older one (a process that isn't entirely guaranteed,
but normally works). New servers understand old ODS versions to an
amazing degree (more than 12 years old), so you can install the new
version then backup and restore with the installed server and tools and
you'll be on the new ODS.

Or, you can run the new software with the old ODS and just forgo some
of the new features. When you want those features, backup and restore.

Good Luck,
