"If you are upgrading from Enterprise Manager 11g Grid Control Release 1 (220.127.116.11.0), then on the Extend WebLogic Server Domain screen, validate the AdminServer host name and its port, and the WebLogic user name. Enter the WebLogic user account password for extending the existing Oracle WebLogic Server Domain to the upgraded release."
For "Upgrade the OMS and the Management Repository" I need weblogic admin server hostname and its port, and weblogic user name and its password.
I don't know the above details.
Is there any file(s) in which hI can find the details.
