    Tried to go to 2.5 and had more serious issues than going to
      2.4.  From the top of my head I don't recall what it was... 

      I've still got the 2.5 binaries laying around.  Do you have a
      successful migration path from 2.2 to 2.5 that I can do? I've been
      told that the 'seen' flags is a big deal for my peeps. I can ( I
      think... if I have to ) write a script that checks the seen flags
      of all the mail on the old system and sets it on the new system...
      but I am hoping to NOT have to do that. I have 185Gig of mail
      files I have to process and if a migration script would do this
      for me, that's the path I'd like to take. 

    we are aiming for 0  / minimal down time and users changes. I
      want to get the mail setup on the new server and just change the
      ip address of the new server to the old server's ip address.
      Hoping to have minimal impact to the users.

I have an old debian box with Cyurs v2.2.13.

I have a new debian box with Cyrus v2.4.17

Is there a documented / official process for migrating mail like
this?  I could not find one.

I have rsync'd the mail between the two systems.

/usr/lib/cyrus/bin/reconstruct did NOT magically convert the system
from the old to the new.

I wrote a script to create the mailboxes and their folders.

After that ( or maybe before... ) I ran:

/usr/lib/cyrus/bin/reconstruct -G -f

and I think that has me close to where I want to be. I have mail
boxes and folders and test users can view their mail.

The 'seen' flags and probably some other flags / acls are not working.

Isn't there a simple upgrade / migrate script path that I am failing
to find?

      Hi Jack,

Why are you migrating to v2.5.x? It has been out for quite a while now?
If you have a lot of users, the 2.2 -> 2.4 upgrade can be painful I/O-wise.

Regards,
Ken
