I am using uDesign theme on our main business site, which I feel is very slow and outdated. I want to migrate this site to GP, but not sure about the process of doing that. If I just switch theme, the site will fully break. Basically it is theme locked, as I am using lots of there short codes to design the contents.
For example, I am using a content toggle to display the itinerary of our tours, which is the first thing to break if I switch theme. Can you suggest anything to fix that? I am using the Classic editor on the site.
Also what should be the workflow to make such migration without any downtime of breaking the site?
Thanks!
