You can perform CommCell migration to move clients and MediaAgents from one CommCell environment to another CommCell environment. You can use CommCell migration to perform cross-server restores or to allow backups to continue in a new CommCell environment. With CommCell migration, you do not need to uninstall and reinstall and re-create all the components for a client or a MediaAgent.
When you move a client from one CommCell environment to another CommCell environment, the entities associated with a client (such as agents, backup sets and subclients) move from the source CommCell environment to the destination CommCell environment. The operation also moves the existing backup data from the source CommCell to the destination CommCell.
