Support for different shapes in a DB system Data Guard association

You can now use different shapes within the same shape type for the primary and the standby databases in a Data Guard association on bare metal, virtual machine, and Exadata DB systems. For example, if the primary database is on an X6 half rack Exadata DB system, the standby database can be on an X7 quarter rack Exadata DB system.

For information on how to enable Data Guard, see the following:
