Hi All,

I have a primary and standby DB using data guard
I want to upgrade oracle to 11G.
I know that primary and standby should have same version even if data guard will not work again.
I want to know what is the steps by steps action to properly upgrade both DB : primary and Standby.

Thanks in advance.

This is described in an appendix of your Data Guard Admin Guide, you know. The idea is that you install the 11g binaries on both primary and standby; shutdown the primary and the standby; mount the standby off the 11g home, start the MRP; upgrade the primary.
So the atandby gets upgraded implicitly, by applying the redo generated during the upgrade of the primary.
