10.4.1 General Restrictions for Using Earlier Oracle Database Releases

Restrictions for using earlier Oracle Database releases with Oracle Grid Infrastructure 21c.

You can use Oracle Database 12c Release 1 and Release 2, Oracle Database 18c, Oracle Database 19c, and Oracle Database 21c with Oracle Grid Infrastructure 21c.

Do not use the versions of srvctl, lsnrctl, or other Oracle Grid infrastructure home tools to administer earlier version databases. Only administer earlier Oracle Database releases using the tools in the earlier Oracle Database homes. To ensure that the versions of the tools you are using are the correct tools for those earlier release databases, run the tools from the Oracle home of the database or object you are managing.

When you install Oracle databases on a Flex ASM cluster, you must set the Oracle ASM cardinality to All.
