Continuous replication starts when an active mailbox database is added to a Mailbox server that is a member of the database availability group. A Mailbox server added as a passive database replica opens a TCP connection to the Mailbox server that hosts the active database replica, and the mailbox database is seeded from the source server to the target server. After the mail database is seeded, continuous replication uses the same process to replicate * * transaction log * * information between the source mailbox and the destination mailbox server. You can change the TCP port used to connect the destination and source replication services. If Windows Firewall is enabled on the Mailbox server, you must add updated replication ports in the Windows Firewall settings. The default port used is * * TCP 64327 new replication port; you can change the replication port by running this command: Set-DatabaseAvailabilityGroup-Identity (name of DAG)-ReplicationPort (new replication port) as part of the replication process in Exchange Server 2013, Mailbox servers that are members of the same DAG replicate the * * content index * *. Each mailbox database maintains a separate content index and replicates the content index on all mailbox servers that contain a copy of the same mailbox database. The health of the content index, which is very similar to the mailbox database itself, is critical for monitoring. For example, if the health of the content index reaches a failed state on a Mailbox server that contains a copy of the active database, the Mailbox server may move the mailbox database to another server that has a normal copy of the content index database. The main purpose of content indexing is to maintain a catalog of key components of e-mail items so that you can * * quickly perform an end-user search or eDiscovery search *. A major change in Exchange Server 2013 is that Microsoft has integrated the FAST search engine for better indexing and search performance.
