Cyrus aggregate compatibility.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We currently have:

       Cyrus Front-End servers running 2.2.12
       Cyrus Back-End running 2.3.16

I have built a new back-end server running 2.4.17.


I plan on adding the new, 2.4 server, to the aggregate, and move all the 
mailboxes.  I would rather not upgrade the front-end servers, since they 
are be retired (and replaced by perdition or nginx).  This move 
motivated by the status of the old SAN disks.

I know that there is a NOSELECT issue, but any shared folders will be 
moved as a group.  Are there other issues?

Specifically, is the proxy/mupdate protocol compatible?

I'm ready to add the new back-end to the aggregate, and run some tests. 
  Thought it might be good to ask here first.

Thank You.

Mike
