· I have two Roon cores in two different locations each with their own subscription (one monthly and one lifetime). Can I synchronize these cores so they share information? The core with the lifetime subscription has more history and playlists that I have used since 2017? Should I just use the same backup file for both cores?
You can if it’s two subscriptions on the same account. Otherwise, you can’t.
If on the same account, just backup one and restore to the other. Once you have done this, Tidal and Qobuz will stay in sync, but you’ll need to install any local music on both.
That makes sense. What if they are being used at the same time. I sometimes have guests at one location using one core while i am at another location using the other. That situation is rare so I think the backup and restore to the other is probably going to be sufficient.
That is a non-issue except, if you make changes on both, independent of each other, those changes are going to get over-ridden on the one that gets restored, as well as play history, etc.
