Introduction
When updating your node, care should be taken to ensure the update goes smoothly. These instructions use the babylonnode CLI tool for an easy update process.
1. Prepare to update
First, if you haven’t already done so, ensure that you have backed up your node-keystore.ks key file. This key file contains the private key that determines your node’s unique address. If anything goes wrong in the update process, if you have your key file, you can always reinstall the node from scratch and use it to recover access to your node.
Next, you may want to consider using a backup node to perform a switch to the updated node with minimal interruption (especially if running a validator node) – or to provide a quick recovery if something goes wrong during the update.
2. Update your node
