This is what I did.
- Both laptops use the exact same directory structure (all files syncd locally from Onedrive)
Old laptop stores MM5 in a Onedrive directory called MediaMonkey
New laptop stores MM5 in a Onedrive directory called MediaMonkey2
On old laptop - Performed database rebuild and then backed up the the DB
Restored DB on new laptop
The path for music files shows as... []\My Music
I tried clearing the DB, re scanning and importing the playlists, which worked but puts all the playlists in the Imported Playlist category and can only be moved out manually (I have 200+)
