Upgrading services

Servers, brokers, and proxies must be at the same release level. When upgrading:

  1. Shut down the furthest-upstream service or commit server and permit the system to quiesce.
  2. Upgrade downstream services first, starting with the replica that is furthest downstream, working upstream towards the master or commit server.
  3. Keep downstream services stopped until the server immediately upstream has been upgraded.
Tip

See the instructions on upgrading at Upgrading the server.
