About Upgrading Your Operating System
Check operating system requirements for new releases, and if necessary, upgrade your operating system before upgrading Oracle Database.
When you upgrade to a new release of Oracle software, the operating system requirements may have changed. If required, upgrade the operating system before upgrading Oracle Database.

Options for Transporting Data to a Different Operating System
If you want to perform a cross-platform upgrade, then check for platform-specific differences that can cause issues with data transport, particularly platform endianness.
You cannot directly migrate or transport data in a database on one operating system to a database on another operating system. For example, you cannot migrate data in Oracle Database on Oracle Solaris to an Oracle Database on Microsoft Windows. You must follow procedures specific to your operating system platforms.
To see the platforms that support cross-platform data transport, run the following query using SQL*Plus:
SELECT * FROM V$TRANSPORTABLE_PLATFORM ORDER BY PLATFORM_NAME;
Oracle provides options that you can use to transport tablespaces in a database that runs on one platform into a database that runs on a different platform, such as Recovery Manaager (RMAN), and methods such as using image copies.
Note:
If the source platform and the target platform are of different endianness, then you
cannot use the RMAN CONVERT DATABASE
command. This process requires
both the source and target platform to be the same endian value. Your available
options are Oracle Data Pump replication, Oracle Data Pump export/import, or
Transportable Tablespace, using RMAN CONVERT TABLESPACE
. If the
platforms are of the same endianness, then no conversion is necessary, and data can
be transported as if on the same platform.
Review the relevant documentation to assist you with cross-platform data transport.
