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 “Data migration example
configuration” (page 45) for an 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.
“Configuration after data migration” (page 46) shows the migration of data after converting
a remote volume into a primary volume.
