Adding a 2.3.x replica

[Adam Tauno Williams]

Looking at
<http://www.cyrusimap.org/docs/cyrus-imapd/2.3.16/install-replication.php>

Reading the quote -

"Rolling" replication means that the "master" server continuously
synchonizes itself with the replica.

- I take this to mean that the master continuously *pushes* changes to
the replica [secondary]?

Is there a recommended/suggested value for sync_repeat_interval other
than the default of "1"?

Is there a recommended method for bringing up a new replica for an
active master (with 1.4 million messages in its mailstore).
