Multi Instance with different port AlwaysOn 2016

Hi all,

I'm configuring a multi instance Always On Availability group with SQL 2016 Enterprise.

I have two server DB-01 and DB-02

I successfully configure AlwaysOn with DAG in default Instance. All works Fine. WSFC works Fine. Perfect.

I have a Big problem installing a second Instance called for example "INSTANCEONE" on both servers.

The second Instance must run on a different tcp port, example 1435. When configuring a Availability Group with wizard i can specify tcp port on the classic login screen (see image) but whet permorm a failover, the AG cannot connect both instances because try to connect with default port.



My questions are:

1) exist a way to configure multi instance AlwaysOn cluster?

2) how can edit the Replica instance configuration to use non default tcp ports?

Thank you !!
