Usage Considerations
Migrating Clients to Another Controller
If there is an imbalance in the network load, the system can rebalance the
load by migrating clients between controllers, either automatically or
manually. Choose whether the clients or routers in the list may be migrated to
other controllers.
Select the connections you want to migrate from the list and click Assign
Interface. The Assign Interface page displays, and lists the selected
connections for approval.
Choose the controller you want to migrate the selected clients to. You can
either choose a specific controller as the target or choose Assigned Controller.
• To migrate all the selected clients to a specific controller, choose a specific
controller from the list.
• To migrate all the selected clients back to their original controllers after a
failed controller is revived, choose the Assigned Controller. Each client can
have a different assigned controller.
You can either let the system select the target interface on the controller, or
choose a specific one.
NOTE: This operation will disconnect CIFS connections if they are migrated to a
different controller.
• To enable automatic rebalance, select
Allow these clients to migrate to
other controllers when rebalancing the network load
.
• To keep the selected clients assigned controller permanent (except during
fail-over) clear
Allow these clients to migrate to other controllers when
rebalancing the network load

Setting the Migration Policy
In case of a controller failure, the system automatically migrates each
connection from the failed controller to another controller to allow clients to
continue their work. This causes disconnections to CIFS clients. When the
failed controller revives, the system can rebalance the load by migrating
clients back to the revived controller automatically. This operation is called
fail-back.
