Funny enough I have just found that I did download an updated scheme that does work with 4.2.3 so if needed I can upgrade

Does going from 4.2.2 to 4.2.3 need any reverts or anything?
I will continue to test "as is" and see what happens, as I say the quick test we have done so far seemed OK...
I was thinking of doing a full upgrade and change the entire site design which is why I wanted to wait...
Do you have any ideas what could go wrong with 4.2.2 and 5.5? just a guide will do, I cant be the only one who has done this Lol ... and someone above even said they have it working... or had as this is an old thread..
