When moving old firebird versions (2.0 and earlier iirc) from 32 bit to 64 bit, you need to backup (with 1.5) and restore (with 2.5). Make sure you use the - default - transportable backup

Note in general it is advisable to backup and restore when migrating between versions as this upgrades the ODS which makes new features available, but in this specific case it is even required because the ODS of older versions of firebird was different between 32 and 64 bit.

Hi.
I want to replace my Firebird 32 1.5.6 with the last  Firebird 64 2.5.3, on 64b

All my databases was created with 32b, 1.5.6 Firebird.

After installed Firebird 64, if a try to connect to database.FDB a received an error

"database.fdb is not a valid database".

Thanks.
