you need to upgrade all the databases to 12cR1?

If you upgrade to ASM 12cR1 and implement Flex ASM, do you need to upgrade all the databases to
12cR1?

A.
Yes. All the databases need to be upgraded to 12cR1.

B.
No. You can run in a mixed 11.2 database instance and a 12cR1 database instance. The 11.2
instance will use the Flex ASM instance of the other server.

C.
No. You can run in a mixed 11.2 database instance and a 12cR1 database instance, but the
11.2 instance will fail if the local Flex ASM instance is moved to another server.

D.
No. You cannot upgrade your database instance to 12cR1.
