Hi Thomas. Noted with much thanks on the assistance. I've never had to run DB upgrades from outside of DB server itself in the past, until I stepped upgrade to 9.3, when I ran into that error. I did a UDL test to see whether my console server is able to reach my DB server but it was unsuccessful. However, my console server is still able to query port to DB server through -netconnection -port in PowerShell. Not sure if this will cause issues with the DB upgrade as the configured port is a custom port. I remember that when I ran the console upgrade application, there was one prompt that indicated that the process was unable to determine whether DB has been updated or not, but I am still able to proceed.
