Upgrading from 2.3.9

• The method used for generating Globally Unique IDentifiers used for replication has been changed to be the SHA1 hash of the messages. If you wish to upgrade the existing GUIDs in particular mailbox(es) or the entire server, perform the following steps in the listed order. Note that is is NOT REQUIRED that existing GUIDs be upgraded.
  1. Zero GUIDs on the replica (reconstruct -g)
  2. Regenerate GUIDs on the master (reconstruct -G)
  3. Regenerate GUIDs on the replica (reconstruct -G)

1. install cyrus-imap, cyrus-sasl (my build), mimedefang-perl-modules, and mimedefang
2. copy the following onto the new host
   • /var/imap/
   • /var/spool/imap
   • /usr/sieve
   • /etc/sasldb2
   • /etc/mail/certs
   • /usr/lib/sasl2/Sendmail.conf
3. make /tmp/VOIPmail for mimedefang-filter VOIP conversion
4. reconfigure sendmail
5. enable the startup scripts (rc.sendmail, rc.cyrus, rc.saslauthd, rc.mimedefang)
   • do I need to add rc.cyrus to rc.local?
6. Upgrade the GUIDs (as per above)
