The main website is just huge and has way too many components installed so I will likely use a launcher and bring components in as I need and copy and paste content. A headache but at leat then I know everything will be compliant and I can also spend time on the design without having any pressure to get it finished quick.
I might try and duplicate the site first and upgrade but I'm not that confident that will work to be honest but for the time it takes worth a try I guess.
