Understanding the Migrate operation
In this operation, the actual migration happens. Service groups on the source are taken offline, so there will be a downtime when the operation is in progress. After the operation is complete, you can use the target cluster to run the application.
In this operation, the service groups in the source are taken offline before detaching the mirror disk groups from the source cluster nodes. This is to ensure data integrity before the final migration. After the mirror disk groups are detached from the source cluster nodes, endian changes are performed on these volumes in the target cluster nodes and the service groups are brought online in the target cluster.
The operation aborts if all volumes between the source and mirror disk groups are not completely synced.
In this operation, verification is done to ensure 100% sync between the source and target clusters. Cluster configuration is completely translated and service groups are taken offline from the source. Replication is stopped for all RVGs of all disk groups part of the migration. Endian changes are performed on volumes part of replication on the target after which service groups are brought online. Secondary site is removed from the primary RVG and the primary RVG is also removed for all the disk groups marked as Create New.
