Listener upgrade 11.1 to 12.1 on Windows
Platform - Windows server 2012
Server has Oracle 11.2.0.4 SE-One installed and multiple DBs running. This has been its config for well over a year.
Now I am prepping to upgrade to 12.1.0.2.0 SE-Two. Software has been installed and the latest bundle patch applied.
