Hi Lionel
Welcome to the forum
You shouldn't have to complete your project before updating
You shouldn't have to export and then import into V2
But
You can never be 100% sure that everything will work 100% successfully every time - watch some SpaceX videos
I would export it somewhere so it's safe, complete it anyway in the existing version and then do the upgrade then see if V2 can bring anything to that project - that's just what I would do
EDIT: Why complete it in the existing version? There are lots of changes to the UI in version 2 and you know your way around what you're using at the moment
NOTE: I'm not a developer I'm just a Grand Master with a shed load of posts and a bit of experience
