Cheeky! Thing is, at FM our production servers more or less track the master branch, so we were running "3.0" from the moment 2.5 forked off, and so our upgrade process only ever really needs to deal with iterative changes. Our accumulated experience is what informs the "upgrade notes" included with the 2.5.0 and 3.0.0 releases (not sure about older versions, I wasn't around then).
This mailing list is the right place to find people with real experience doing big-bang upgrades. :)
Cheers,

Hi mate,
I think (and say think :) )I finally found a method. Although I'm testing it deeply... it seems (say seems too :) ) 2.4 is compatible with a mail spool in 2.3 (at least with my config). So I'll try to upgrade first to 2.4 and later to 3.0 setting up a replication from 2.4 to 3.0. Would be fine if Bron, Ellie or someone at Fastmail could tell something about it to us :) :)
Cheers!

At least in manual mode (not rolling)?.The replication protocol in 2.4 is not compatible wit 2.3.There is no easy way. I'm rsync'ing one account at a time between 2.3 and 2.4 with IMAP/POP and LMTP access disabled, followed by a reconstruct, and then enabling IMAP/POP and LMTP access.Many terrabytes to go.You could also look at imapsync but its slow.Cheers.---EGOITZ AURREKOETXEADepartamento de sistemas944 209 470Parque Tecnológico.

I was planning to set up Cyrus 3.0. I have seen all works properly except for theunexpunge command because as someone stated here, a reconstruct -V max was needed.The problemis that this reconstruct command, takes ages and I'm not able to keep the service offline somany time. So I have been thinking in the following scenario :- Cyrus 2.3 master -> Cyrus 2.4 slaveGet this 2.4 slave ready and set it as master. But here comes my first doubt. Does the 2.4replication work with the 2.3 replication?. Can in this pair, both (the 2.3 and the 2.4) beboth master and slave?. I mean to switch roles in the pair. Make one become master and theother slave and vice versa?.Let's think now Cyrus 2.4 is ready and working.- Now, I would set up a new 3.0 slave. I know 2.4 could replicate with 3.0. So I would get the3.0 ready and then set 3.0 as master. Can in this pair both the 2.4 and 3.0 be master andslave?. Meaning again to the same role switching commented before... to make one to be masterand the other slave or vice versa....I'l will end up with 2 3.0 master and slave... but I need to trace the path...Does anyone see any other way?.Best regards,---EGOITZ AURREKOETXEADepartamento de sistemas944 209 470Parque Tecnológico.
