Hi,

It's still not really clear to me what to do to use replication with GUID.

E.g. I'm running a version < 2.3.10 and upgrade to 2.3.10

I stop master and slave.  Upgrade software. Remove provide_uuid=X from 
cyrus.conf.  Add guid_mode: sha1 to imapd.conf on both master and 
replica.  Start replica, start master.

install-upgrade says:

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)

But it doesn't mention my case.  Should I run -G on the master and 
replica?  Or isn't it necessary? Or must I do it.  Does it matter if the 
master/replica are(n't) running?

What is the consequence if I don't zero the GUIDs?  Or don't regenerate 
them?

Thanks in advance,

Rudy

PS I don't have any trouble of summarizing the answers to something that 
can be added to install-upgrade.
