Disagreed. Upgrading from 2.2 to 3.0/3.1 is not rewrite half your stack. I literally just upgraded a 1.5yo project at work from 2.2 to 3.1 in a couple of hours. I had 1 undocumented issue which took the bulk of the time to fix. Everything else was pretty much namespace fixes or EF being more explicit.

2.2 to 3.1 is probably the easiest upgrade I’ve ever done. You wanna talk about mvc 1 to 2/3, now that was a painful upgrade.
