Upgrade applies to previously installed MDP, starting from 10.x release only, to the latest version release. If you are using an updated version of MDP, "Upgrade MDP" will not appear on the list of selections.
Upgrading M3 Metadata Publisher to M3 Core release
If you have generated an MDP BE System for Components and Text Search before you run upgrade, you will be notified of the required tasks to perform right after you run upgrade. Click OK to continue.
Verify the information of the (old version) client to upgrade.
Verify that the new version to be used is the latest and click Next.
After the upgrade, all the existing MDP BE System will be deleted. You will need to generate a new MDP BE System both for System Configuration and Components and Text Search.
For more information on how to generate MDP BE Systems for System Configuration and Components and Text Search, see M3 Metadata Publisher Administration Guide.
