migrating from normal configuration to virtualdomains

[Riccardo Veraldi]

Hello,
I am migrating my actual cyrus config to one supporting virtual domains.

the problem is how to copy the old /var/spooll/imap  to the new one 
supporting virtual domains


my domain is for example domain.com
the old configuration has the mailboxes root in /var/spooll/imap

if I enable virtual domains and I set up domain.com as default domain,
can I simply rsync my /var/spooll/imap from old server to new server 
without having troubles ?

thank you

Rick
