My experience was very difficult going to 7.2 to 7.3 because of a change 
in the behavior of NetworkManager with respect to IPv6 but once I had it 
figured out (thanks to people on this list) it worked out quite well and 
I kept NetworkManager.

But I certainly understand why some don't want to do that.
