Thanks for replying Stefan.
I logged in to web client from Prod site and DR site, no matter it picks DR - Prod as default order.
If i right click Prod site and select "Create Protection Group" or right click DR site and select "Create Protection Group", no matter always it thinks by default my DR site is the protected site and i have to change radio button every time to point to my prod site while creating protection group.
Is there no advanced setting even to specify this order or to set my deafult protected site?
