We are looking to migrate from a 2.3.7 server to a 2.4.18 server. I was hoping to set up the cyrus murder/aggregator and move the existing server behind that. While doing some reading and research, I came across the following mailing list thread. I was wondering if it's still the case that the frontend needs to be the same version as the older backend? https://lists.andrew.cmu.edu/pipermail/info-cyrus/2010-May/033061.html
Yes, it is still the case that a newer frontend may try to proxy commands to an older backend that it does not understand/support.
As a result, backends are usually upgraded before the frontends.
Aside from the compatibility between frontend and backend, there was also a comment about having to recompile the sieve filters per the other post below. Is that still the case moving from 2.3.7 to 2.4.18? Are there any other gotchas to look out for? https://lists.andrew.cmu.edu/pipermail/info-cyrus/2010-May/033056.html
Sieve scripts compiled with 2.3 *should* be compatible with 2.4. There is no mention of recompiling in the upgrade notes.
