I am just in the middle of a similar procedure right now, although I have a single-server setup. I have never used or investigated murder or any other way to run a multi-server Cyrus setup, so I don't know how this affects the procedure. I assume you'll be running the same version of Cyrus on the new server. If not, you should check the upgrading docs about possible database format incompatibilities (bdb vs skiplist). I'll also assume that your Cyrus directories are in default locations. With single server, things are fairly easy. Install Cyrus on a new server as usual. Create the /var/imap directory with permissions set as specified in the docs (cyrus:cyrus, mode 750) On old server, tar up the directories /var/imap/user, /var/imap/quota and /var/imap/sieve. Also, tar up the directory containing your user mailboxes - /var/spool/imap. Transfer these archives to new server and expand them in their default locations. Copy over the mailboxes.db file from old server to new server On new server, run mkimap as explained in the documentation. This creates all the other necessary subdirectories and files in /var/imap. Of course you also need to think about how your users authenticate to the service. In my case this is done simply by sasldb database, so for me it was as easy as copying the sasldb file from old server to new. OK , actually it was not *that* simple - since my old and new servers use different bdb libraries, I used db_dump to dump the sasldb database on old server and db_load to reload it on the new server. But still straightforward enough. That was basically all. I started the service on the new server and everything worked. I also ran 'reconstruct -f' and 'quota -f' just in case. -- Toomas ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
