Yes it will all transfer. Good idea to back up Roon Core before you do it.
I lost everything once, and it was extensive playlists that were the most painful loss. You can download a pdf of those also before transfer.
Moving Roon to new core
I am in the process of moving my Roon Core and collection of ripped CDs from a MacBook Air (M2) to a Roon Nucleus One with a 4 TB internal SSD. Running out of hard drive on the Mac (can't upgrade HD as it is soldered-in). I plan to de-authorize the MacBook Air and then authorize the Nucleus One. Will be same Roon Account.
Will my current playlists and Tags transfer to the new Roon Core/Nucleus One? Anything special I need to do? The Nucleus One is connected by USB cable to a Moon 390, Moon 330A and Magnapan 1.7i speakers. Thanks for the help.
