dovecot - Mar 2012 - Advise on upgrading from a jurassic version - please help.

Hi all,

I have inherited an old Dovecot installation which is causing headaches almost
every day.

I know that one of the rules says "Don't bother asking questions about
v0.99.x versions. They're no longer supported."...but please bear with
me, this will be quick as I only need some advise from experienced Dovecot gurus
out there.

I have read the Dovecot documentation and there are instructions to upgrade from
0.99.x to 1.x and so on... my question is: can I upgrade from 0.99.11 to 2.x
directly or is it a massive leap? If so, what do I have to keep in mind? This is
a production system so I should not break anything... or at least have a
rollback plan...

Thanks a lot in advance!


Regards,

Martin

http://wiki2.dovecot.org/Upgrading/1.0 points out a few things:

 - rename .subscriptions -> subscriptions
 - rename .customflags -> dovecot-keywords
 - default pop3 UIDL format changed
