You can use the upper few bits of the record number to indicate which of
your databases is current. This technique is mentioned briefly in Neil
Rhodes' book here:

Yes, my app searches 5 databases this way. I use the upper 3 bits of
the record number to indicate which one (0 through 4) and the lower 13
bits for the actual record number. Using 13 bits imposes a limit of no
more than 8,192 records, but that's not a problem in my case.
