I have a older Cyrus 2.2 version setup and running in production.
I want to move to a newer Cyrus 2.4 system with minimal downtime.
The goal is 1) limit down time and 2) keep the SAME ip address for the
users imap configs.
I can convert my existing Cyrus 2.2 ( Debian v6 ) to Cyrus 2.4 ( Debian
v8 ) but will be down around 8 ( at least ) for the two debian upgrades
and converting 200gig of Cyrus 2.2 mail to Cyrus 2.4 - indexes and what not.
I was thinking.. maybe another approach would be to setup Cyrus Murder (
2.2 ) on my existing Cyrus 2.2 box and connect it up with a new Cyrus
2.4 server ( on a new Debian v8 box ) and just move mail accounts over
one at a time until all of the mail was off of the old box. Once all of
the mail was off of the old Cyrus 2.2 box, I could then upgrade that to
debian v8 and Cyrus 2.4 and then have 2 systems that the mail could be
split between.
Can I run a Murder 2.2 server and have it talk with a Cyrus 2.4 IMAP box
or do the versions have to be the same?
Thanks - jack
