How do you “kill the process”? Command prompt? Like this?:
c:\Metabase jar location>taskkill /IM metabase.jar
And “…restart the server”? Like this?:
c:\Metabase jar location>java -jar metabase.jar
Reference to Upgrading Metabase where it says “If you are running the JVM Jar file directly, then you simply kill the process, replace the .jar file with the newer version and restart the server.”
