Yes @mrv777 is right in this case. You can use this guide here to transfer your existing data, but you’ll need to use an empty drive to get set-up with umbrelOS first.

How to Synchronize a New Bitcoin Node from an Existing One

Advanced users can take advantage of the following methods to synchronize a new node with an existing one. Please be cautious as these methods are not natively supported in Umbrel.

Method 1: Transferring Blockchain Data

The steps below are for copying data from an existing Linux machine to a new Raspberry Pi, but the steps are similar for other combinations of devices.

1. Flash UmbrelOS to a microSD card and boot the Raspberry Pi with your SSD attached.
2. Complete the Umbrel setup process. Your SSD will now be formatted for Umbrel use.
3. Go to the settings page and shut down Umbrel.
4. Remove the SSD and attach it to a Linux machine with the full blockchain.
5. Copy the blocks and chainstate directories on the Linux machine to ~/umbrel/app-data/bitcoin/data/bitcoin directory on the SSD.
6. Remove the SSD from your Linux machine, plug it back into your Raspberry Pi, and power it back on.
