Migrate one Oraichain node to another

Migrating your node to a new machine doesn't have to be complicated. Follow this structured guide to ensure a smooth transition with minimal downtime.

[!CAUTION] ⚠️ Do not put priv_validator_key.json on two running nodes simultaneously. Your validator will be jailed forever !!!

1. Back Up Your Current Node Information

Before starting, backup your node's essential files to prevent any data loss:

cp -r ~/.oraid/config/priv_validator_key.json ~/.oraid/config/node_key.json ~/backup/

These files are crucial for maintaining your validator identity.

2. Set Up a New Node

Initialize a new node to prepare for the migration. Follow the full node setup guide here. You can reuse the same moniker as your existing node.

3. Sync the New Node with the Network

Ensure your new node synchronizes with the network before migration to minimize downtime. Start your new node with a persistent connection to an existing network node.

oraid start --p2p.persistent_peers="<existing-node-id>@<ip>:<port>"

Let it fully sync before proceeding.

4. Shut Down the Old Node

Once the new node is synced, gracefully stop the old node:

systemctl stop orai

This step prevents conflicts between the two nodes.

5. Transfer Node Data to the New Machine

Copy the backed-up files to the new node:

scp ~/backup/priv_validator_key.json ~/backup/node_key.json <new-node-ip>:~/.oraid/config/

Ensure the new node retains the same identity by using the copied keys.

6. Restart the New Node

Apply the changes by restarting the new node:

oraid start

Monitor logs to verify it is running correctly.

7. Verify Voting Power and Node ID

Run the following command to check if your node has successfully migrated:

oraid status && oraid tendermint show-node-id

  • If the voting power and node ID match your previous node, congratulations! 🎉 Your migration is complete.

  • If not, double-check the copied files and restart the node.

  • Common mistakes include not stopping the old node first or copying files before the new node has finished syncing.

8. Import Your Wallet (Optional)

If you need to restore your wallet on the new node, use:

oraid keys add <wallet-name> --recover

Alternatively, use the explorer to manage your wallet effortlessly.

Final Thoughts

Your old node remains unaffected throughout the process. If needed, you can always revert by restarting the old node.

🚀 Happy validating!
