As far as i’m aware it SHOULD work just fine… i’ve opened projects from a friend who has ‘Artist’ many times.
If you have 3rd party plugins you might have to enter their paths in the plugin manager if they’re not in one of cubases’ default locations… that’s for another post though.
Yes, matjones is absolutely correct. LE-projects open fine in Pro, no need to import anything. In case of missing plugins check out the plugin manager.
