Hi,
We are creating a secondary R81.10 management server in Azure. ( We will be upgrading entire environment next year to R82)
The primary server was built using Azure marketplace. marketplace
Per docs we are building the secondary server with the same marketplace app.

In this doc here it says to select Secondary server when creating the server. : Overview of Management High Availability
(Video shows R80 but is on the R81 Doc.)
But the first time setup wizard does not seem to run on first login and there are no options in the marketplace tool to select Secondary.

In the Smart Console the Secondary button is greyed out:

Can we just proceeded with syncing the servers with both servers set as primary ?
Primary and Secondary both have the latest hotfix installed.
There also does not seem to be anywhere to set a SIC key. I am guessing this would be available if this was a secondary server.
Also. the new secondary management server seems to take the public IP address by default.
Is this safe to change to the private post install ?
thanks
