Selected data structures in the source cluster will be migrated to the target cluster.
Selected data structures in the source cluster will be migrated to the target cluster.

Prerequisites:

* Only a single migration can be run simultaneously.
* The target cluster must be an enterprise cluster or Viridian cluster.
* At least one data structure name must be provided in the migration configuration file.
* The data structures given in the migration configuration must exist in the source cluster.

Further Information:

* Existing data structures on the target cluster will be skipped.
* It is recommended that the source cluster is put in read-only mode before the migration starts.
* Viridian clusters supports at most 14GB of primal data. If you try to migrate more than that, the failure
is expected. You can consider Viridian Dedicated for larger data migrations.
