I am a node operator/miner, what do I need to do?

If you have a running node, you need to

• Suspend the running operation of the node
• Replace the executable file named “conflux” in the run directory of the original node program with the Conflux executable file of the Conflux v2.4.1-testnet node program.
• Restart the operation of the node

If you start a new node, you can download the latest version of Conflux v2.4.1-testnet and run it.

What will happen if I do not upgrade the nodes or refuse to upgrade?

It is strongly recommended to upgrade your node, this upgrade aims to improve node stability.
