Upgraded
from SolarWinds NetPerfMon 10.3.1 to 10.6.
IIS for the site will not start; “This Web site cannot be started. Another Web site may be using the same port." Also, SolarWinds Orion Module Engine will not start.
try this:
Remote to whatever server Orion is installed on and go to Orion Service Manager, turn everything off and back on.
I didn't have the IIS issue but I did get the engine issue, make sure you let your team know (if you work with a team) that you'll be shutting down the services on that server so potentially you won't be getting any messages if a server were to go down.
Hopefully that helps!
