Do you still have the switch you used previously?
I’m wondering whether the new switch is preventing discovery of the ST core.
edit: I suppose that may not be possible with a fiber network. Don’t know how that all works. Is the new switch unmanaged or managed?
I would also check to see if you haven’t by any chance set a static IP for the SonicTransporter when it was on the previous network, if you did, you’ll also want to switch over to DHCP and set a Reserved IP in your router configuration.
I’ll check but I don’t think so. The Night Hawk router has changed the ST IP address a few times. I’m having a lot of trouble with the new EdgeRouterX SFP so until I get it properly operating I won’t be able to transfer anything.
The Sonic Transporter is set to DHCP. One strand of the fiber is broken so we have to run another cable. When that’s done how do I migrate Roon to the new fiber network? I’m still not clear on that.
If you are just plugging the ST into a different network, you don’t need to do anything. The database really won’t be affected. Your devices will need to be re-identified to new IPs, but I’d think Roon will recognize their MAC addresses and likely will keep the names, etc.
If you kept your music on the ST, it will also be recognized.
But make a database backup via Roon anyway. Just for safety sake.
The general idea with migrating a core (to a new machine) is to make a backup of the system via Roon, plug in the new machine, and restore the backup to the new machine. You’ll probably be asked to deauthorize the old machine. But for you, it should be very easy.
assuming you havent made it a fixed IP address ie its still DHCP it should find an address and be visible again. A fixed IP address might still work but will depend on the new router networking settings.
