Replication Read-Only Mode when Migrating to New Data Center

Demonstrates a how replication read-only mode supports migrating from one data center to another, and how existing backups on a downstream recovery appliance can be accessed read-only by an upstream recovery appliance.

Figure 15-4 shows the databases in local data center backing up to its RA-x. In the example, all of the local databases need to be moved to the remote data center, and RA-x is to be decommissioned.

The databases in the remote data center are created by cloning them from RA-x. Then a replication server is created on RA-y as the upstream, and RA-x as the downstream. On RA-y, a protection policy is added to the replication server with READ_ONLY=TRUE.

The databases in the remote data center start backing up to RA-y. Should a database need to be recovered, backups on local data center RA-x remain accessible through RA-y until RA-x's backup's are obsolete and RA-x is decommissioned.
