Node Migration

In the event of a node crash or if you intend to move it to a new system or instance, you can perform a smooth migration by following these steps:

Important Note

Before migrating your node to a new system, please ensure that the old system has been completely shut down and validators are no longer participating in block attestation or proposal on the old system.

Running same validators on multiple systems simultaneously will lead to slashing penalties due to double signing.

Step 1: Download the latest permissionless Stader node CLI​

• Visit the following link to download the latest version of Stader node CLI for permissionless node operators: Download Stader node

Step 2: Install Stader node CLI​

• After downloading the latest version of Stader node CLI, follow the provided instructions to install it by visiting the following link: Install Stader node

Step 3: Configure the node​

• Configure your installed Stader node by following the provided steps on this link: Configure Stader services

Step 4: Node synchronization​

• Once your Stader node configuration is complete, your ETH clients will begin syncing. This process may take some time as it involves syncing both the ETH1.0 and ETH2.0 chains. Please be patient and wait for the sync to complete. You can check the sync status using the command: ~/bin/stader-cli node sync

• The estimated time for synchronization is around 3-4 days without a checkpoint URL and around 1-2 days with a checkpoint URL on the Mainnet.

Important Note

Before proceeding with the next step on your new setup, please ensure that the old system has been completely shut down and validators are no longer participating in block attestation or proposal on the old system.

Running same validators on multiple systems simultaneously will lead to slashing penalties due to double signing.

Step 5: Recover your wallet​

• Once the node is fully synced you can recover your node and validators using the wallet recover command : ~/bin/stader-cli wallet recover

• Enter your password and the wallet mnemonic to recover your wallet (Node and Validators)

Step 6: Check your node and validator status​

• To check the status of your recovered node, using the following command: ~/bin/stader-cli node status

• To check the status of your recovered valdiator, using the following command: ~/bin/stader-cli validator status
