migrate all variant of old user id to new user id
I am working on Single sign on project. I need to change all user id to match with a network id. That is no problem. However, I need to be able to bring along all variant for old user id to the new id. Do you know is there a Bapi or a way to do that? I know I can have user login as old id and create a copy of the variant but that will be a lot of work for user and they may complain. I donu2019t want users to do anything except change their id. All the process should be invisible to users.
Is there a way to do this? If so, please let me know.
