Help with AlwaysOn

Hello all,

I have a primary site with a WFC. All data is replicated via alwayson to secondary site.

Data is being replicated asynchronously. The failover/failback process is working as intended.

I pretend to active the DR site with the prodcution site still avaiable (yes want to have both sites up for a few time) to do some tests and after tests are done revert the all situation. 

I tried to found some information on how to do it but i wasnt able to find.

Can anyone help me with this?

Regards,
