Can I use an Standard Edition (SE) standby database for an Enterprise Edition (EE) primary?
No. This becomes and issue when customers star to use EE features like partitioning or wan to run the standby as a primary. Also, this violates our pricing model and should not be done or suggested to the customer. Since a standby database is a block-for-block copy of the production database the standby database is the same flavor of Oracle — e.g., SE or EE — as the production system. See the following for clarification.
