Hi,

I was going through note id Mixed Oracle Version support with Data Guard Redo Transport Services (Doc ID 785347.1). It says

"

  • Physical Standby
    • Mixed Version Support between a Primary database and a Data Guard Physical Standby is NOT supported at all until Oracle Database 11.2.0.1.  From Oracle Database 11.2.0.1 it is possible to configure the Physical Standby database with at a higher patchset or major release Primary database for purposes of a migration to new hardware provided that after a switchover to that standby, the database is not allowed to open and is immediately upgraded in the normal manner. "

With this comment, is it possible to have primary database in 11.2.0.3 and standby database in 11.2.0.4? If so, what value should be set in compatible in standby database? Are there any other pre-requisites to  be considered before setting up?
