Question seems quite clear to me Sean

*IS* that statement correct?
I think I would always backup with the current version and restore with the
new one just to be on the save side even if the 32bit and 64bit are running on
the same machine as we keep being told not to simply copy a database? Since I
probably expect a change of machines as well the backup/restore is logical.
Needing to recompile the UDF's for 32 or 64 bit is not so obvious, but if you
are only using the in built UDF's that is already handled.

Actually what would happen if you tried un-installing a 32bit version and
re-installing same 64bit version - can it even be done - I've only run 64 bit
since moving back to Linux.
