I am New to Opmanager.

Need understanding of deployment of Opmanager on Failover.

we have 2 server for MSSQL clustering and 2 for opmanager

I have read and understood the working mechanism of  BEFailover table, need to know how the communication happen  between 2 opmanager server is through port 80 or any other setting needs to be done for the failover.

Also suggest if I go with the standalone server deployment of Opmanager and later need to change to high availability what is the configuration setting needs to be done and  how much time it takes.
