Oracle 10.2.0.4 => 11.2.0.2 Migration using DBUA

Hello,

I got one question to the following step in Oracle Migration:

Oracle 10.2.0.4 => 11.2.0.2 Migration using DBUA: Step: "Run the Net Configuration Assistant BEFORE using DBUA"

I´ve got the 10.2.0.4 DB on the same server I want to Install and migrate to 11.2.0.2. After installation of the 11.2.0.2 software I want to run the Net Configuration Assistant to configure the 11g listener.

Do I have to UNinstall the 10g listener before?

No need to Un-install, just shut it down.
;)

Thank you! So the old listener does not using the 1521 port and the new one can be installed. Am I right?

right.

Thanks,
