Updating my site
I designed my website in Divi 5 originally, but before knowing about the mastery course and Krafter. I'm making a pretty significant update to my site now and want to apply all these principles. Do I need to start from scratch? Is there a way to apply Krafter to my existing staging site?
You can install it, but you'll probably have to do some or a lot of tweaking.
Kim Waag Mak made a video showing how to convert a site from Divi 4 to Divi 5. It's not exactly the same as redesigning a site that was originally built in Divi 5 using KrafterPRO, but the overall principles are quite similar.
A suggestion, is on the design system, set your go-tos as the defaults; then you will not need to tag everything. For example, a text module: mine is defaulted to "Body Text"
