Well, it depends on the databases. It might be easy (just use File...
Get External Data... Import to import the objects from one into the
other); it might be nightmarishly difficult, if you have "the same"
table in both databases, with Autonumber primary keys with duplicate
autonumber values in the two tables, and with a dozen related tables
propagating those autonumber values.
Post back with a bit more description of the nature of the databases
and we'll try to help.
