Question about database upgrade to 11.2.0.4 on RAC database
Hi,
We are getting ready to upgrade our RAC databases to 11.2.0.4 from 11.2.0.3 and I'm facing a problem with planning for the upgrade.
I understand that to complete the upgrade properly you need to upgrade the grid instance first but I'm wondering if I can run the 11.2.0.4 upgrade in one of our cloned instances just to make sure the upgrade scripts run ok.
I thought I could do an out-of-place upgrade and then run all the upgrade scripts. After I'm finished testing, I could revert back to the 11.2.0.3 OH and re-clone the database.
Will this work, will it cause and issues for the grid instance?
