I want to learn few points from your migration scenario. <br>
<br>
Few days back I migrated my 32 bit
cyrus-imapd-2.3.7-12.el5_7.2 to 64 bit
cyrus-imapd-2.4.17-6.el6.x86_64 server<br>
I faced the below problems , how you are handling the below
points on 64 bit server in your case ?<br>
<br>
1) How do you maintained the seen-unseen mail flags. <br>
2) I came across duplicate email download issue in email client
. <br>
When IP of 32bit server shifted to 64 bit server , then for
those client who have setup POP3 account with "leave copy on
server" in email clients for them emails got download again. <br>
<br>
On 64 bit server there was no changes in /etc/hosts and DNS A
records and /etc/resolve.conf , it was exactly same as 32 bit.<br>
<br>
Request you to please share your comments / suggestion which
need to take care for above issues. <br>
<br>
Regards<br>

<pre wrap="">Hi,
I'm planning and testing the migration of a IMAP mail server based on
cyrus 2.3.8 with about 3TB of mailstore, 300 users and a lot of shared
folders (with shared flags (group permission with +w)).
The old server is a 32bit one and the new one is 64bit virutual machine.
as now I've succesfully used this procedure:
- Rsync of all mailstores /var/lib/imap and /var/lib/sieve
- rm -v /var/lib/imap/db/* /var/lib/imap/db.backup1/* \
/var/lib/imap/db.backup2/* /var/lib/imap/deliver.db \
/var/lib/imap/tls_sessions.db /var/lib/imap/mailboxes.db
- ctl_mboxlist -u < /tmp/mboxlist.txt
- ctl_cyrusdb -r
- tls_prune
- ctl_cyrusdb -c
- cyr_expire -E 3
The last command took about 24 hours to complete and if understand right
It converted cyrus mailbox DBs from v9 to v12.
I wonder if the first cyr_expire could run even with the service started
and if it should be better to run a reconstruct on all the mailboxes in
place of this cyr_expire.
Last but not least, do you think that sieve filters should be recompiled?
Any other hints?
Thanks
Giuseppe
