How to update Cyrus IMAP 2.3.16 to 2.4.5

[Lucas Zinato Carraro]

 - Install newer version and run reconstruct ?
Yes, i use this procedure and works fine.

-------------------------------------------------------------------------------------------

 - I know that exist a new index format, its safe to convert  2.3.16 to  2.4.5 ?
Yes its safe

--------------------------------------------------------------------------------------------

- Any related problem ?

I have some problems with some mailboxes.
To solve i remove  cyrus.* ( .index, .squat,  .cache )
and run a reconstruct in this mailbox.

-----------------------------------------------------------------------------------------------

- Install older version and run reconstruct ?

Yes, i test this procedure with a server with 1000 mailboxes.

---------------------------------------------------------------------------------------------------

No big problem with  upgrades from 2.3.16  to 2.4.X


Regards
Zinato
