Mass forwarding on UWL notification from one user ID to another

Hi All,

We are migrating to new User IDs due to privacy issues with the old IDs. What I do understand is that there is a standard Function Module to transfer pending work items from the old ID to the new one.

Is there a way to transfer all notifications (read and unread) from the one user ID to the new one programatically?

Thanks,

Ananth
