Smartzone joining cluster after setup ?

[philip_francis1]

Hello, I have two existing vSmartzone controllers both fully configured. Now I want to join one of them to the other as a cluster. 
However I cannot find info on how to do this outside of the Setup Wizard and there does not appear to be any option in the GUI cluster settings.

How do I achieve this without using the setup wizard ?
Thank you.

Philip,

The option to join the SZ to a cluster is available only during the Setup Wizard.

Sir, I understand that only identical VSZ can be in same cluster.

If I have an existing vSZ-E 6 in GCE, and I want to add another into the same cluster, how do I do that? I cannot find download vSZ 6 for GCE. The latest vSZ for GCE available is 5.2. Does this mean I am stuck with one?
