I am running Bitcoin Knots+Electrum server on a pi4 with 8gb ram and an external 2TB SSD. This pi4 do not have Start9 OS installed as I built the node from scratch following guides such as raspibolt.
The blockchain is fully synced.
Now I got myself a 4TB nvme SSD for my Intel NUC. This NUC will run Start9 OS and the intention is to turn it into a bitcoin node. The NUC has 16gb ram.
The question is, how do I copy over the bitcoin blockchain data from the 2TB external SSD to the 4TB nvme SSD so that I do not have to download the blockchain data again?
During the initial setup on the Nuc, you can use the recovery transfer option to transfer the entire server from the 2TB external.
In your case, after you’ve done the initial flash, you’ll just connect the 2TB external to the Nuc for the initial setup. If for some reason, you do NOT want to transfer your sever intact, but want to migrate just Bitcoin’s Blockchain data, we have a guide for that as well.
Regarding “migrate just bitcoin’s blockchain data” using SSH, is it also possible to directly connect an external drive containing the full blockchain data to the StartOS server and simply copy it over? Thanks!
“Possible,” yes. “Simple,” no. This is due to the fact that the drive is encrypted, the service is containerized, and there is no graphical file manager, or even a terminal emulator baked into StartOS.
The guide I pointed to is the best way to transfer Blockchain data between StartOS servers.
I see I read this wrong. My apologies. This being the case, we do not have a guide for your specific case. If you understand the commands, and you understand how to get to your current blockchain data on the 2TB drive, you can probably adapt the migration guide to accomplish the same thing. If not, it will probably just be easier to do a new IBD on your new StartOS server.
Thank you. I really appreciate your response. As matter of fact I tried to adopt the guide but it didn’t work out so decided to start from scratch. Now the blockchain is fully synced and Electrs is setup. Now only thing to do is to connect sparrow wallet to the node.
