eb: Person's or User Account Merging - Logged on behalf of RRS Onke Ruda

Could you please advise if it is possible to merge a two eb account documents history, for example, loading documents and history of an old account to a new account and have the old account deleted but leaving behind the document history to the new account?

If this can be done, could you please provide me with print screens of the steps as this is not covered in the eb documentation?
