Configuration for data migration

To make a copy of a volume in a remote location, configure a cluster of storage systems in the
remote location with enough space to accommodate the volume. See
example configuration.

How this configuration works for data migration

Suppose you want to create a complete copy of a volume for an application to use in a different
location.
1. Configure a cluster of storage systems in the new location to contain the copied volume.
2. Create a one-time remote snapshot of the volume onto the cluster in the new location.
If your application server uses multiple volumes that must be in sync, use a script to quiesce
the application before creating remote snapshots.
[Optional] You can create regular one-time snapshots and use remote copy to move the
snapshots to the remote cluster at your convenience.
3. On the cluster in the new location, make the remote volume into a primary volume.
4. Configure the application server in the new location to access the new primary volume.
