Yeah, I decided to bite the bullet tonight, cleared the system cache, fired up the VPN, changed region to Canada and snagged the OTA update.
It was a totally painless upgrade from MM to Nougat. I didn't lose my APN settings either. In fact, I ended up with 4 APNs vs the 2 APNs I had on MM! I had to add back a couple of system apps (contacts and clock), but that was also a non-event.
I am still on EXT4, but I'm content with that for now. I am happy I did NOT have to FDR and reinstall and tweak all my apps!
Great job on the update, OP.
