Upgrade 11.2 to 12.1 without using "Upgrade Oracle Grid Infrastructure" option

edited Mar 15, 2017 9:09AM in Database Install/Upgrade/Opatch (MOSC) 4 commentsAnswered

We have a standalone database(NOT RAC) that is using ASM. ASM runs from a GI (Grid Infrastructure) version 11.2.0.3. I want to upgrade GI to version 12.1.0.2. My high level plan is 

Download GI 12.1.0.2

Execute runIsntaller 

"Choose Install Grid Infrastructure software only"

Install GI in a separte GI Home. In the meantime GI 11.2 is still up and running.

  Apply latest DBBP patch to 24968615 DBBP 12.1.0.2.170117 

 

When we have downtime we shall now perform these steps:

Follow 1422517.1 to deconfigure the 11.2 GI Home. Next reconfigure the newly installed c12 GI to point to the same storage area.

 

 

Is the above a proper way of doing the upgrade. I don't want to have runInstaller do the upgrade because this will increase the downtime.
