I was not very clear with my language in my original message. When I said active pair, I meant a pair that is currentIy in production and fully upgraded. 

Instead of upgrading the intended pair, I upgraded the one that I had already done but on the other partition while left me with 17.1.3 or both HD1.1 and HD1.2. 

I can't explain what the issue is/was, but after some time, I am able to proceed as I typically would as all the previously mentioned grayed out options are now available to me.
