Monitor 2025 with 11.4 Web Adaptor - Uninstall the 11.4 WA first?

Question

Hello -

I feel like I should be unregistering and/or uninstalling the 11.4 web adaptor that is currently registered with my 2024.1 monitor deployment before I begin the Monitor 2025 Server and Agent upgrade.  But I'm not seeing guidance either way in the setup and config docs.

Hi @DavidColey, you won't have to do it before, but you will need to uninstall 11.4 Web Adaptor and install 11.5 Web Adaptor for Monitor 2025:
