Upgrading M3 Metadata Publisher to M3 Core release
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, you cannot select "Upgrade MDP" on the list of selections.
Important
After the upgrade, all the existing MDP BE Systems are deleted. You must generate a new MDP BE System both for System Configuration and Components and Text Search.
See information on how to generate MDP BE Systems for System Configuration and Components and Text Search in M3 Metadata Publisher Administration Guide.
