Upgrading Nexus from 3.22.1-02 to 3.25.1-04

I am attempting my first upgrade of Nexus Repository manager (as I’m fairly new to Nexus) on a Windows install and I’m not really understanding the method to upgrade. I followed the steps from the upgrade page. I have unzipped the new version into the nexus install dir then I run the command \nexus-3.25.1-04\bin\nexus.exe /run . Is that correct? and is that all I need to do?? because it still shows as being version 3.22.1-02.

I think you need to setup your service again - https://help.sonatype.com/repomanager3/installation/run-as-a-service#RunasaService-Windows
