Ok I've tried this upgrade several times now and each time the same thing happens.
First time, it all worked fine, then a day later I went to the site and I just got a time out waiting for the site to load, and on the server noticed hundreds of php.exe processes had been spawned.
So I restored the site. Now each subsequent upgrade the same thing happens. As soon as you have the upgrade complete notice and click to return to the forums you get nothing, just it trying to load.
Has any requirement changed with version of PHP or MySQL with this upgrade?
