100% true on post #3. Here is my 5 cent advise: Whatever you import, do first all your assets. The built-in ones import from DLS (at least should be updated), and once you see in CM no faults and or missing dependencies, proceed to import the routes and sessions. If you import everything at the same time, most for sure, the faulty and missed dependencies will create problems and will be hard to repair. Not going into details here, but it is my experience.
