[Dovecot] Upgrading Dovecot on CentOS 4 from 0.99 to 1.x

[Josep L. Guallar-Esteve]

(sorry for my previous message, I sent it by mistake before finishing it)

Hello,

We  have a production mail server running dovecot 0.99 (dovecot-0.99.14-1.rf). 
We are getting several errors corrected in dovecot 1.x versions: 

* corrupted inboxes (garbage at beggining of mbox files), 

* corrupted index files (Error: Corrupted file 
index /home/jsmith/.imap/Drafts/.imap.index: Sequence 6 not found from binary 
tree (6 msgs says header)), 

* others (Error: fcntl() failed with mbox file /var/mail/jsmith: Resource 
deadlock avoided), etc.

I'm planning to upgrade using the instructions found at dovecot's wiki. On 
http://atrpms.net/dist/el4/ it is offered in 3 different versions:

* dovecot 1..0.15-1_73.el4  
* dovecot 1.1.19-1_96.el4
* dovecot 1.2.5-0_100.el4

I have a separated test system, where I'll test upgrading from 0.99 to final 
selected version, to discover any possible gotchas found while upgrading.

Two questions:

1. Which version is the recommended to upgrade? I'd like stability and as 
little problems as possible over anything else, as we have a simple set up.

2. What is the preferred upgrade method? straight upgrade? (099 -> rpm -Fvh 
dovecot-1.2 ? Or upgrading one release at a time? (0.99 > 1.0 > 1.1 ...)


Thank you in advance for any recommendation.


Regards,
Josep
