You control Roon via a Roon Remote, an iPad would be ideal.
Good idea to read up first, I hope you already have Roon backups … but if not that’s one aspect you can practise / setup before hand. These days I have Roon scheduled to take a backup, in the early hours, each night. Works like a charm.
I have read the articles, and the sections linked on it.
Since the Roon Core is preinstalled on sonictransporter, I would skip that step, and point a controller (my iPad ) to the new Core on sonictransporter.
I currently have my music files on the PC current Roon Core is located. Once sonictransporter comes, that PC will no longer be in use for Roon, so I will have to change my watched forlder to the NAS I have that I have a copy of all my music library. I have a third backup of my music library on a USB drive as well.
I realize that the backup of Roon database (as discussed her and KB linked) is separate and nothing to do with my music files, but I am a bit confused how they will both be tied in together on the new Core on sonictransporter
Since you buying a used one I suggest you delete the whole Roon installation.
Even on my new SonicTransporter I did, as well as delete all files.
You can browse the directory from file manager in windows.
Delete, reboot, install Roon, upgrade, transfer backup.
On an iPad you probably need an paid app like the FileBrowser.
I am only backing up the database. Wouldn’t everything go away once I point Roon Core to different hard drive than currently pointed to? I plan to no longer use the PC where my music files are currently sitting and Roon Core is pointed to, and use the NAS which has the same files.
