Do i have to put the provide_uuid in imap & lmtp services both in master
and replica cyrus.conf or only in the master cyrus.conf ? Does the
sync_machineid has to be set in the imapd.conf of the replica ?

When you set up a replica for the first time with a master already in
service, do u have to first manually synchronize the mailboxes and only
after set the rolling replication ? Is there a way to reinitialize
"rolling" replication on the master ?
