But, this particular server is being retired from imap service once the replication server is in place.

The new back-end server has about 4 times the space. So, while I can continue to use the rsync server during the Cyrus upgrade, it will run out of space---possibly as soon as January a the current rate of growth. OTOH, upgrading cyrus on the rsync server would allow me to test replications earlier, and during the upgrade.... Mike -- Michael D.
