My upgrade from 11.0.1 to 11.5 just tanked! Here is my Case # 784008 Created: Upgrading to NPM 11.5 and cannot continue install. Still no response from Solarwinds support. I am getting this configuration wizard error stating multiple instances are running and there is an active running on the additional webserver. I have not even started to upgrade the additional webserver. Very irritating must say! Has anyone out there experienced this during their upgrade if so what did you do to fix it?
