Yea I had the same issue. I ended up closing all my lightning channels and moving funds completely off my node, to be safe and sure I don’t end up loosing anything.
I disconnected my old ssh 1tb with the old data and connected my new drive and installed umbrel.
Now instead of downloading the entire block chain again from scratch I actually reconnected my old 1tb that had all the blockchain data downloaded already and I copied the data folder from old drive to the new one and rebooted.
Boom data was all there, just missing a few percent which took a day or 2 to complete.
