Migrating to a Different Server

No problem, one of your amazing community members has developed this guide. After you have created a new machine and finished all the steps up to and including Creating new linux users, follow this guide.

On Your New Machine

Download Binaries via APT Repo

sudo mkdir -p /etc/apt/keyrings
curl -fsSL repo.chainflip.io/keys/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/chainflip.gpg

Verify the key's authenticity

gpg --show-keys /etc/apt/keyrings/chainflip.gpg

Add Chainflip's Repo to apt sources list

echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/chainflip.gpg] https://repo.chainflip.io/perseverance/$(lsb_release -c -s) $(lsb_release -c -s) main" | sudo tee /etc/apt/sources.list.d/chainflip.list

Installing The Packages

sudo apt-get update
sudo apt-get install -y chainflip-cli chainflip-node chainflip-engine

Adding your existing keys

sudo mkdir /etc/chainflip/keys

Note: After this you don't need to generate new Signing Keys, you can skip that phase and continue to the command below with your old Seed Secret.

Loading Your Signing Keys

YOUR_VALIDATOR_WALLET_PRIVATE_KEY << change to Your private key from Metamask.

echo -n "YOUR_VALIDATOR_WALLET_PRIVATE_KEY" | sudo tee /etc/chainflip/keys/ethereum_key_file

YOUR_CHAINFLIP_SECRET_SEED << change this text to the old Secret Seed

export SECRET_SEED=YOUR_CHAINFLIP_SECRET_SEED

echo -n "${SECRET_SEED:2}" | sudo tee /etc/chainflip/keys/signing_key_file

Generating a Node Key

Finally, we need to do a similar process one more time. We need to generate a separate key that is used for secure communication between Validators. This time run:

sudo chainflip-node key generate-node-key --file /etc/chainflip/keys/node_key_file

You can check that the command worked by running the following command:

cat /etc/chainflip/keys/node_key_file

You should see the contents of the files printed to your terminal.

Back Them Up & Copy Your Validator ID

sudo chmod 600 /etc/chainflip/keys/ethereum_key_file
sudo chmod 600 /etc/chainflip/keys/signing_key_file
sudo chmod 600 /etc/chainflip/keys/node_key_file
history -c

Make sure to update your config file with the IP address of the new VPS. Otherwise you'll get slashed once you start the engine on the new VPS.

Do not run two instances of your Validator at the same time. You will almost certainly be slashed. Make sure you turn off your old server before you turn on your new one.

After that make sure to stop the engine and the node on the old VPS by running:

On the Old VPS

sudo systemctl stop chainflip-node.service
sudo systemctl stop chainflip-engine.service
sudo systemctl disable chainflip-node.service
sudo systemctl disable chainflip-engine.service

On the New VPS

Setup the config file as explained in Engine Settings section.
Then start the node and engine services as explained in Start up section.
