# Upgrading P2P Layer

Upgrading the P2P layer of the subnet to fix bugs or make general updates requires each node to restart its node.

It is suggested to use a blue-green deployment strategy by gradually migrating connections to the new version with no breaking changes.

Optionally, subnets can utilize Docker/Kubernetes/Systemd for rolling updates that automatically handle the restarting of nodes to the newest version.
