Transitioning sketchup shop to sketchup pro

Hi I have been using sketchup free since it came out and got a sketchup shop subscription last fall. I am getting a computer that will run the pro version of ske5chup tomorrow and plan to transition all of my modeling work to that computer and invest in sketchup pro. Wondering 2hat advice would someone who has lots of time on the web modeler but no time on the desktop modeler or with layout. Extensions to get how to move models over. Any advice would be much appreciated.

You don’t need an extension at all.
All your models are on Trimble’s servers. And you can also download them if you want.
