We use some simple perl scripts to "rename" a user in Cyrus:

Then we just delete the old mailbox.  The other step is changing the 
username in LDAP as well, obviously.

We have about 35,000 users right now, and while we discourage frivolous 
changes to usernames, we do allow changes for obscene usernames (happens!) 
and legal name changes.  I wouldn't call username changes "common" here, 
but we do at least one a week.
