# man cvt_cyrusdb
# /usr/lib/cyrus/bin/cvt_cyrusdb
Usage: /usr/lib/cyrus/bin/cvt_cyrusdb [-C altconfig] <old db> <old db 
backend> <new db> <new db backend>
Usable Backends:  berkeley, berkeley-nosync, flat, skiplist, quotalegacy

Dump to flat file, copy to new server, convert back to desired bd format.
[Should work, untested here. Inspired by 
http://wiki.linuxwall.info/doku.php/en:ressources:dossiers:cyrus:repair_skiplist]

Or you copy by imapsync.
