A.2 Multiversion Upgrade Procedure
This procedure refers to an intermediate upgrade and final upgrade. An
intermediate upgrade is defined as a version of the operating system that you
need to install to reach your final version.
The final upgrade is the version of the operating system that you want to be
running on your system at the end of this process.
Important
You should not plan to stay at the intermediate version. If you need to
upgrade to and run the intermediate version, use the normal upgrade
procedure located in the installation manual for that specific version.
