I purchased a Roon Nucleus about three years ago and it’s been in storage. I’m currently running Roon on my desktop, which has all my tags, playlists, and preferences. I’d now like to shut Roon down on the desktop and begin using the Nucleus as my Core without losing any of my data.
System details:
Core (target): Roon Nucleus
Network: AT&T fiber gateway (router + modem)
Streamer: iFi Zen Stream
DAC: Mytek Brooklyn+
Analog chain: DAC → preamplifier → amplifier → stereo system
Control: Roon app on tablet
Could you please provide the recommended steps for this migration, and confirm any updates or compatibility checks I should do before moving the Core?
Thanks in advance for your guidance. (Tagging @noris in case you saw my earlier message — thank you!)
If not, I suggest you start their and get back if you have any issues.
Note: If the migration to the Nucleus does not go well, your current Roon Server will still be operational and can continue to be used since the process is non-destructive in relation to the original server (although you may have to unauthorize the Nucleus - depending on how far you got before you encountered issues). Thus, you don’t have to be scared of losing data if it goes wrong on the first attempt.
Edit: The link that @Suedkiez posted above may have more specific information relating to the Nucleus - but the principles are the same no matter what type of server you are migrating to.
As you know, I’m migrating my Roon Core from a desktop PC to a Roon Nucleus. The Nucleus is headless (no monitor), is visible on my home network (I can see it in my router), and my desktop is on the same network. I don’t use a NAS—this is about moving the Core and keeping my tags/playlists/preferences intact.
My questions (most important first):
Initial access (headless): How do I connect to the Nucleus the first time—via the Roon app, a specific IP/URL, or another method?
Management interface: Is there a separate GUI/web admin page for the Nucleus, and how do I reach it?
Core identity: Do I migrate my existing Core/database to the Nucleus, or should I sign in fresh on the Nucleus and then restore?
Backup restore: Once I can access the Nucleus, what are the exact steps to restore my desktop Core backup on the Nucleus?
All of these questions are answered in the articles linked above by @Suedkiez , @bearFNF and myself.
If you have a problem understanding any of the points in these articles, then be sure to explain exactly what you are having difficulty with and reference it to the relevant article (and point within the artcle) from those linked above.
I’ve reviewed the instructions carefully. My home network recognizes the Nucleus and shows its IP address (see attached screenshot). However, when I try to connect via the Roon Remote app, it can’t find the Nucleus (screenshot attached). Because of this, I’m unable to reach the setup or migration pages.
Your second image shows the Nucleus connected by Ethernet with an ip address of 192.168.1.82 on your router’s Web UI (with the router on ip address 192.168.1.254).
So far, so good. The Nucleus is s in the same subnet as your router which is as it should be.
However, your screenshot also shows partial details of two WiFi devices bother connected via 5GHz WiFi (DASA19). Whilst it is hard to tell because the info for neither device is completely visible, it looks like these devices are not being allocated IPv4 addresses but they both have IPv6 addresses.
By contrast, the Nucleus does not get allocated an IPv6 address. I don’t know why (unless the version of RoonOS currently installed is old enough that it doesn’t include support for IPv6). .
You are then trying to connect to the Roon Server using a tablet (connected via WiFi) - which possibly only has IPv6 access when the Nucleus only has IPv4 access. If this is the case, it would explain the failure to connect.
Consequently, it looks like there is something strange with your network. I think you need to look further into the WiFi connectivity and ensure that WiFi devices are being allocated ipv4 addresses
Have you tried connecting to the Nucleus using the Roon client on your desktop?
Have you updated (reinstalled) the Nucleus firmware using the Nucleus WebUI which can be accessed on:
Again, if your WiFi devices are only getting IPv6 addresses, then you may need to use a Web browser on your desktop (which is hopefully getting bother IPv4 and IPv6 addresses) in order to access the Nucleus WebUI.
