Is it possible to add 3rd secondary node on existing AG group with Asynchronous ?

Hi All,

Currently in my environment we are using SQL server 2012.

We setup Alwayson with synchronous commit.

Details of existing AlwaysOn: one primary and two secondary.

Primary: On-Premise server.

Secondary1: On-Premise server.

Secondary2: Azure VM.

Requirement: We need toadd Secondary3 New Azure VM on same AG with asynchronous mode or synchronous mode.

                                                                                                           Or

                          We need to create one more AG on same DB and add the new replica with asynchronous.

Is it possible above 2 option in this scenario?

My cluster environment is Manual failover only not auto failover.

Could you please guide me how can I do this?

Thanks,

Raj K.
