@ErichStyger , I'm not really sure I understand which is your preferred way to use an existing project with a new IDE version.
In that thread, you suggest not to share workspaces between different versions of the IDE and instead to import projects from the old workspace into the new workspace. To me this insinuates a strict separation of projects, i.e., the new IDE only accesses the new workspace which contains a copy of the project (copied not linked from the old workspace). Consequently, the projects in the old workspace are only accessed using the old IDE.
Here you seem to suggest to do linking (not copying) with the import.
However, linking projects seems contradictory to the notion of strict separation. In that thread you reason that issues with backward and forward compatibility can be resolved using different workspaces for different versions. I understand that. Therefore I'm confused why now you suggest linking instead of copying projects.
Just to be clear, this is not a discussion about whether to use drag&drop or the import wizard (from Quickstart Panel) to import a project, it's about selecting "copy projects" or linking projects into the new workspace. Both methods (drag&drop and import wizard) of copying and linking.
