10g to 11gr2 RAC upgrade

edited Sep 5, 2013 11:18AM in Database Install/Upgrade/Opatch (MOSC) 6 commentsAnswered ✓
How to upgrade a 10g rac database of 65TB in size to a 11gr2 setup. Everyone's reccomending to to out of place upgrade which i agree.

THis is the high level plan i had in mind.

Create a new 11g cluster

Based on SAN replication replicate the asm disks from the 10g cluster to the 11g cluster.

Modify the appropriate permissions to the asmdevices/disks to work with new grid user and other groups that were introduced in 11gr2.

I need some help after this.

Should i get 11g grid asm to open up the disks that got replicated from the 10g cluster and the add instance/database to it. And then just upgrade the database alone to 11g?

Howdy, Stranger!
