ok. I rsync /var/spool/imap/user now.
Does it matter:
new server has one subdir per character:
a
b
c
d

while old server has:
auser1
auser2
auser5

Yes, the binary is here and is able to:
# su cyrus -c /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

I will give it a try in the evening when I can stop the server for a moment.
Forgive me my questions, but which files do I have to convert:
