Importing Cubase SL .all files into Cubase artist 8.5

Does anyone have an idea about importing and converting old Cubase SL .all files into Cubase Artist 8.5. I am doing a re-mix of a song recorded with Cubase SL. If it’s possible I’d like to be able to extract tempo, pan, individual track, etc. data that is contained in the old .all format, the equivalent of the new .cpr project file extension.

I have a similar question, but bringing in Cubase SE 3 .cpr files into Cubase 8.5 Artist… can anyone help?
