# Upgrade servers, brokers, and proxies

Ideally, servers, brokers, and proxies are all at the same release level, but this is not a requirement. To learn more about upgrading, see:

- Upgrade the server, where the upgrade requires both:

  - Upgrading the P4D binary.

  - Upgrading the P4D database.

- P4 Broker, where the upgrade only requires replacing the Broker binary.

- P4 Proxy, where the upgrade only requires replacing the Proxy binary.
