I may well be looking in the wrong place; but I cannot seem to find any Upgrade Documentation for HAP+ anywhere. We are currently on version 9.1.501.1430 and I was going to try and upgrade to version 9.7 today. I have downloaded the zip file and realise that I will have to reapply all my changes to the CSS files after the upgrade, but I am unsure where to go next.
Is there a definitive upgrade document and am I OK to jump from version 9.1 straight up to version 9.7 or do I need to apply every upgrade file incrementally?
Thanks in advance,
