Mixed Cyrus Version Murder?

[Wesley Craig]

This is just how UMich upgrade from 2.2.x to 2.3.x.  We contributed a  
number of changes to 2.3.x to facilitate the functionality.  I would  
expect it to "just work", but you should of course rigorously test  
it.  In particular, you might want to test ACLs, quotas, annotations,  
POP, and other non-mail data.
