Turn Off Mailbox Server on Single-Server Node When all mailboxes have moved from the single-server node to the new mailbox server node, disable the Mailbox services on the original single-server machine. 1. On the original single-server node, disable the following mailbox server components: • mailbox. zmprov -l ms <singleserver.com> -- -zimbraServiceEnabled mailbox • logger. zmprov -l ms <singleserver.com> -- -zimbraServiceEnabled logger • stats. zmprov -l ms <singleserver.com> -- -zimbraServiceEnabled stats • spell. zmprov -l ms <singleserver.com> -- -zimbraServiceEnabled spell • convertd. zmprov -l ms <singleserver.com> -- -zimbraServiceEnabled convertd If archiving was installed, disable it as well, zmprov -l ms <singleserver.com> -- -zimbraServiceEnabled archiving 2. After the mailbox services are disabled, verify that antispam, antivirus, ldap, mta, snmp, proxy, and memcached are the only services on the original single-server node. zmprov -l gs <singleserver.com> | grep -i serviceenabled
