In all the tests I have done, if I "upgrade" a server to 64 bit version, it can access the all the DB's created on that computer. I have not tried to copy DB from one 64 bit to another 64 bit server.

Databases in ODS 11.1 (I believe), are transportable between 32 and 64

backup on 32 bit and restore on 64 bit to upgrade the ODS.
