I in fact did tried once to re-installed the Umbrel in the same laptop after I remove it. It actually works. I just replaced the new bitcoin folder to the one with my full node. Just not sure it works if I am using a different device this time. Anyway, thanks for your feedback.

Can I use back my existing Bitcoin Node for my new Raspberry Pi 4 device?

I think in theory it comes down to finding where your full blockchain is saved now, and configuring bitcoin core on your new machine to persist the blockchain wherever you moved it to. I would expect this to “detect” that the blockchain is already downloaded and pick up where it left off. Unfortunately I don’t know how to configure Bitcoin core to tell it where to source/store the blockchain.
