About PMM Server upgrade

Upgrade PMM Server before Clients

• When upgrading PMM, always upgrade the PMM Server before upgrading any PMM Clients.
• Make sure that the PMM Server version is higher than or equal to the PMM Client version. Mismatched versions can lead to configuration issues and failures in Client-Server communication, as the PMM Server may not recognize all parameters in the client configuration.
• For the UI upgrade option, Watchtower must be installed with PMM Server
