La ODS 8 corresponde con Interbase 4, que ya es bastante, pero bastante, pero muy viejo.
Me encontré esto en el bdn, espero te sirva de luz:

B 6 Open Edition may not prevent you from connecting to an On Disk Structure (ODS) 8 (IB 4) DB. Doing so can corrupt the DB. IB 6 commercial editions do prevent this. In general, any InterBase server version supports connecting to DBs created by the previous version, but not older DBs. However, when upgrading server versions it's always a good idea to make a transportable backup under the old IB server version, do a test restore to ensure that you have a good backup, upgrade the server, and then restore under the new server version. This ensures that the database ODS is up-to-date.
