I’m looking to move my BTC node with my Pi 4 lighting channels to a new install on a much stronger PC using the latest version of Umbrel (1.x.x). Can anyone tell me what the safest strategy is to do this without having to close all my channels?
I thought about using the explanation from this link below and using the backup script, and then performing an AUTO IMPORT on the first Umbrel boot (1.x.x), but it wasn’t clear to me in the explanation if this works from Pi 4 to the Linux device, since it is about migration on “linux devices” and Pi migration is just a sd card update.
Can someone please clarify if this backup script procedure will work from the old Umbrel Pi4 to a new Umbrel Linux Device?
If this script doesn’t work, will this script permanently stop the Pi4 from working, or can I recover it if everything fails?
I finally was able to migrate my umbrel 0.54 on Pi4 to a umbrel OS 1.x on a PC.
The procedure that work for me:
Installed the umbrel OS 1.x on the new PC, using a usb stick
The new installation must be made in a new store device that has more capacity than your old install.
After install do not reestart it, shutdown the pc, wait the next steps.
Shutdown the Pi4
Open your Pi and remove the SSD / NVME that has your apps, lightning node etc (not the sd card with your old umbrel install)
Plug the SSD / NVME with some adapter in a working usb of the new PC.
Now you can do the first boot on the new Umbrel install on your PC
It should start the Migration process, for me took several hours and after that, it restarts by itself and everything was working. Log with your old Pi 4 password.
Extra Tips: If the migration process do not start, you can either try another USB port and restart it (never create a user on the new umbrel install)
If something fail you can remount your Pi as I suppose the migration process do not write any new data to your old SSD / NVME.
If your new Umbrel PC migrate properly and your node being online, never turn on your Pi again without formatting it.
