About Upgrade Restrictions

If you are using two or more Oracle Fusion Middleware products of the same or different versions in a single, supported, Oracle Fusion Middleware configuration, you must consider the interoperability and compatibility factors before planning the upgrade.

Interoperability

In the context of Oracle Fusion Middleware products, interoperability is defined as the ability of two Oracle Fusion Middleware products or components of the same version (or release) to work together (interoperate) in a supported Oracle Fusion Middleware configuration. Specifically, interoperability applies when the first 4 digits of the release or version number are the same. For example, Oracle Fusion Middleware 12c (12.2.1.0) components are generally interoperable with other 12c 12.2.1.4.0 components.

Compatibility

In the context of Oracle Fusion Middleware products, compatibility is defined as the ability of two Oracle Fusion Middleware components of different versions (or releases) to interoperate.

For a list of products and features available in Oracle Fusion Middleware Release 12.2.1.4.0, see Products and Features Available in Oracle Fusion Middleware in Understanding Interoperability and Compatibility.

When performing the upgrade of your hardware or software, verify that your Oracle Fusion Middleware software is certified to support the new operating system or computer hardware. For more information, refer to the following resources:

Note:

When you upgrade your system to Oracle Analytics Server, Oracle Analytics Server grants some new permissions to the existing application roles so that your users automatically get access to the new features in Oracle Analytics Server.

If you migrate your system using a snapshot (BAR file) that was created in an earlier release, you must review how Oracle Analytics Server assigned permissions to application roles.

To review the permission sets available for Oracle Analytics Server or to change any of the default assignments, see Grant or Revoke Permissions Assignments in Managing Security for Oracle Analytics Server.
