Migration from cyrus 2.0.16 to cyrus 2.2.8

[Mikael]

Hello,

I am planning a migration of our mailserver which is currently hosting the 
mailboxes with cyrus imap 2.0.16, but I am unfortunatly not familiar with 
cyrus.

The new server would use the distribution's package which is cyrus imap 2.2.8.

I imagine that simply "detarring" the content of /var/spool/imap/ from the 
current server to the new one won't be enough...

Could you please tell me which steps I'll need to follow regarding this 
problem ?
