• Adapt user rights: assuming that transfer copies all user rights to the new namespace, we will need to cleanup the user list.
• Check with AB that everything has been taken care of in order to prevent shutdown because original project seems deprecated (mailto servicedesk on August 07. Ticket#2022080709000013)
