Migrate published links between accounts
It would be helpful to be able to transfer hosting of published InDesign links between licenses of the program - for instance, if someone moves from one institution's license to another and does not want their existing links to become inactive, or if somebody leaves a company and the work that they uploaded on their license needs to stay online. The main reason this would be helpful is to allow stability of the links, rather than having to re-upload and then make sure that all interested parties are given the new updated link.
"if somebody leaves a company and the work that they uploaded on their license needs to stay online"
I think this part of your request is already available under team or enterprise licenses controlled by the institution's account manager.
