Parallel upgrade from version 9.5.0.x to version 10.1.0.x

About this task

How to upgrade your environment using a parallel upgrade procedure. You can either perform the parallel upgrade using a bottom-up or a top-down procedure.

If you choose to upgrade your environment top-down, then the agents get upgraded progressively after you have upgraded the master domain manager and its backup. This means that new features and enhancements are not available on all of your agents at the same time. If, instead, you choose to upgrade your environment bottom-up, then the agents are upgraded first, and new features and enhancements become available after themaster domain manager and its backup have been upgraded.

This procedure is documented in less detail than other procedures because it is less widely used.
