While awaiting my MOS CSI access to be approved For Exadata HW issues so I can open an SR, I have a question. We are about to apply QFSDP for BP 22 on one of our full RACK X3 Exadta servers. Currently, the Grid Infrastructure (GI)/DB SW is at 18.104.22.168.0 and teh storage SW is at 22.214.171.124. Our last BP was 19. BEFORE we apply the BP 22, we want to upgrade the clusterware to 12c - but not the DB (that will come later). This is a high level question which I have discussed with several Oracle techs, but wanted to see what the experience/opinion is while I await access to my CSI. Can you have your Grid Infrastructure (GI) running at a higher version than that of your your storage server? The tech I spoke to said that all GI/DB SW should be at a version that is NO GREATER than that of the storage server - meaning a 12c version of the GI would not be compatible with a lowere version of the storage server. Thank you in advacne for any guidance.
Seems you want to do a lot in one go here.
For 12c (grid and rdbms) on Exadata it is recommended to upgrade your FW to 126.96.36.199.0 first.
My advice would be to patch up 11g to BP22 and when done start planning the 12c upgrade (keeping the 11g dbhome).
