Since my guide is taking ages to get approved, I’ve decided to share it here as a response. I hope you find it helpful. * * * #### ⚠ **Important Safety Warning** ⚠ If you attempt this migration, proceed with extreme caution. Double-check every step to ensure you are not doing anything stupid. Above all, ensure that LND is **never running simultaneously** on both the old and new Umbrel instances. Broadcasting old or invalid channel states may result in penalty transactions, causing the loss of all funds in the affected channels. **DISCLAIMER** : I take no responsibility for any losses caused by mistakes during this migration. Proceed at your own risk. ### Migration Steps #### **1) New Umbrel: Install umbrelOS** Set up [umbrelOS](https://github.com/getumbrel/umbrel/wiki/Install-umbrelOS-on-x86-Systems) on your new device. #### **2) New Umbrel: Initial Setup** Log in via the web interface, create an account, set a password, and install the **Bitcoin** app from the App Store. #### **3) New Umbrel: SSH Access** While Bitcoin is installing, access the new umbrelOS via SSH. Open a terminal on your computer and connect using: ```auto ssh umbrel@NEW_UMBREL_IP ``` Enter your password when prompted. #### **4) New Umbrel: Stop Bitcoin App** Wait for Bitcoin to finish installing and let it run for about a minute. Then stop the Bitcoin app via the web interface or SSH: ```auto umbreld client apps.stop.mutate --appId bitcoin ``` #### **5) New Umbrel: Modify `sudoers` File** Run the following command to edit the `sudoers` file: ```auto sudo visudo ``` Add the following line to the end of the file: ```auto umbrel ALL=(ALL) NOPASSWD: ALL ``` Save the changes by pressing **CTRL+X** , then **Y** , and finally **Enter** to confirm. #### **6) Old Umbrel: Transfer Bitcoin Data** You’ll now transfer the blockchain data (`/blocks` and `/chainstate` directories) from the old Umbrel to the new one. It is not necessary to stop Bitcoin on the old Umbrel. Access the old Umbrel via SSH: ```auto ssh umbrel@OLD_UMBREL_IP ``` Run the following `rsync` command to transfer the data: ```auto rsync -rav --progress --rsync-path="sudo rsync" /home/umbrel/umbrel/app-data/bitcoin/data/bitcoin/chainstate /home/umbrel/umbrel/app-data/bitcoin/data/bitcoin/blocks umbrel@NEW_UMBREL_IP:/home/umbrel/umbrel/app-data/bitcoin/data/bitcoin ``` Wait for the data transfer to complete. It took 2 or 3 hours in my case. #### **7) New Umbrel: Start Bitcoin** Start the Bitcoin app on the new Umbrel via the web interface or SSH: ```auto umbreld client apps.start.mutate --appId bitcoin ``` Your new node should sync quickly. #### **8) New Umbrel: Install Lightning** Install the **Lightning** app from the App Store, then stop it via the web interface or SSH: ```auto umbreld client apps.stop.mutate --appId lightning ``` #### **9) [CRITICAL] Old Umbrel: Backup Recovery Data** Write down your recovery seed phrase and ensure you have an up-to-date copy of the **Static Channel Backup (SCB)** file in case anything goes wrong. #### **10) Old Umbrel: Stop Lightning** Stop the Lightning app on the old Umbrel via the web interface or SSH: ```auto umbreld client apps.stop.mutate --appId lightning ``` #### **11) Old Umbrel: Transfer Lightning Data** Use `rsync` to transfer LND data from the old Umbrel to the new one: ```auto rsync -rav --progress --rsync-path="sudo rsync" /home/umbrel/umbrel/app-data/lightning umbrel@NEW_UMBREL_IP:/home/umbrel/umbrel/app-data ``` This should take only few short minutes, depending on the size of your `channel.db` file. #### **12) New Umbrel: Verify `channel.db` Checksum** Calculate the checksum of the `channel.db` file on the new Umbrel: ```auto sha256sum /home/umbrel/umbrel/app-data/lightning/data/lnd/data/graph/mainnet/channel.db ``` #### **13) Old Umbrel: Verify `channel.db` Checksum** Do the same on the old Umbrel: ```auto sha256sum /home/umbrel/umbrel/app-data/lightning/data/lnd/data/graph/mainnet/channel.db ``` #### **14) New Umbrel: Start Lightning (DO NOT START THE OLD ONE!)** If the checksums match, start the Lightning app on the new Umbrel via the web interface or SSH: ```auto umbreld client apps.start.mutate --appId lightning ``` #### **15) Old Umbrel: Uninstall Lightning** If the new Umbrel is functioning correctly and channels are online, uninstall the Lightning app from the old Umbrel. **⚠ Important:** Never run the Lightning app on the old Umbrel again. #### **16) New Umbrel: Revert `sudoers` Changes** Remove the line you added in Step 5 by running: ```auto sudo visudo ``` Remove the corresponding line and save by pressing **CTRL+X** , then **Y** and **Enter**. * * * Congratulations! Your migration is now complete. ✅ --- _[View the full topic](https://community.umbrel.com/t/migrating-umbrel-home-to-proxmox-vm/20177)._
