I am trying to do the same, but the only guide I’ve found requires two raspberries and two disks:

How to migrate LND (or other app) to new installation of umbrelOS

Recently, I had to move my Umbrel server to brand-new hardware. Since my Lightning Node has over 40 open channels, I was determined not to close them because of the migration. This presented the challenge of safely transferring the Lightning Node and Bitcoin Core to a new umbrelOS installation while minimizing downtime. After some research and testing, I came up with a reliable process, which I’d like to share here. This method should also work similarly for migrating other Umbrel apps. …

It would be wonderful if someone had a lighter procedure.
