[Dovecot] Migrating Dovecot 0.99 to 1.0stable
Hi,
I'm planing to move a big mail server currently under Dovecot 0.99 to Dovecot 1.0 stable. One problem I had once when doing this was that all the UIDL had to change and that all users using pop3 and leaving their messages on the server had to re-download all of them, which is annoying. I'd like to know to the UIDL really have to change when migrating from 0.99 to 1.0stable or if this was a configuration problem on my side. Are there any tips for this to be as transparent as possible for the users ?
Thank you.

I just have a simple question regarding the UIDL compatibility between Dovecot 0.99 and 1.0-stable. Do the UIDL change between both versions, and if yes, is there a way that they do not change, so that pop3 users leaving their mail on the server do not have to re-download all af them ?
Thank's for any answers !

They shouldn't change. pop3_uidl_format specifies the UIDL format, and the default is the same as with 0.99.x. If the UIDLs change, there is some problem.. Are you using mbox or maildir? The default UIDL is generated from UIDLVALIDITY and UID. With mboxes UID is stored in X-UID headers and with maildir in dovecot-uidlist file. As long as 1.0-stable can read those the UIDL shouldn't change.
