Are we talking full client/server install here, or just local InterBase?
I suspect the latter. Migrating the database from IB4 to Firebird or IB6
is likely to be the easy part. You can experiment by backing up the
database and then restoring it to the new server of choice. Whether your
16-bit client application will be able to connect to it or not is
another matter.

Yes and no, but the core api is unchanged and it is that api which is
used fopr all access to the database.
