Change the control node

This task changes the control node in a cluster when you need to specify the exact unit you want to become the control node.

The best method to change the control node is to disable clustering on the control node, wait for a new control election, and then re-enable clustering. Use this procedure when you must specify the exact unit you want to become the control node.

Caution

If you must specify the exact unit you want to become the control node, use the procedure in this section. Note that for centralized features, if you force a control node change using either method, then all connections are dropped, and you have to re-establish the connections on the new control node.
