While it _is_ true that the documentation ships with the distribution, it 
assumes
that one is upgrading on the same machine. I just finished with an 
identical (?)
upgrade Cyrus IMAPD 2.0.16/SASL 1.5.24 on a Digital AlphaServer TRU64 v. 5.0
to Cyrus IMAPD 2.1.9/SASL 2.1.7 on SuSE 8.0. I used scp to copy the /var/imap
and /var/spool/imap directories. Then, make sure to do this (before you run 
rehash):
         find /var/spool/imap -exec chown cyrus:mail {} \;
         find /var/imap -exec chown cyrus:mail {} \;
(assuming that your user is cyrus and your group is mail). The gethostname()
call on TRU64 UNIX returns the FQDN, and on SuSE, of course, it does not.
So, I had to add the servername: and loginrealms: to be the FQDN. If you are
using sasldb for authentication, you will have a group of users in the
oldserver.your.domain.com realm in the new sasldb2 database (it would be 
nice to
be able to interactively change the realm as the conversion is being 
done!). In my case,
the new machine was taking over the FQDN and IP addresses of the old one.
I could not do any testing until I could shut down the old server and 
change all
of the hostname references in the Apache config, /etc directory, et.al.
