If you want to migrate _all_ 2.1 accounts to the 2.2 server, couldn't you
just directly transfer the mailspool and the other files to the new server
using rsync or something. (If you have different DBx versions on the
servers, the db files have to be converted too). That's what I did once
migrating from 2.0 to 2.1.
