if you're migrating the mail rather than physically moving the disks
the only consideration I can think of would be any endianness issues
in the Dovecot index files. you can safely delete them and they will
be re-created. it would be worth trying this before you migrate - and
if you discover that there is no need to rebuild the indexes, then
don't bother.

the same may apply if you're moving the disks, but you'd have to check
whether OpenBSD has support for endian-independent access to the
filesystem.

other than that, it should be very straightforward :)

grant.
