I ended up picking another NEW roon account for the MBA and let the earlier roon stay in my MBP. Good for roon …
My database is in a 4TB Ext drive that I attach with either MBP or MBA.
Hope this arrangement will work … I have 13 days to ascertain it …
That will work, however it’s not really necessary, unless you are planning to use Roon on one computer at a different location and have people still use Roon at home.
If you only use Roon at home, you could move Roon to the new Air, then wipe Roon off the Pro and then install Roon as a Remote on the Pro (if you want to still use the Pro as a control for Roon). When installing, when it asks, just say you want to run as a Remote and then connect to the core on the Pro.
