Hi SharePoint experts!
Does anyone know is it possible to change site collection user id or create a new one with specific ID. (SPUser.UserId) I know the property is exposed only with getter.
If you wonder why. We have Document Set collection with about 50K sets. A user id is associated with an access function, for some reason a new user id was created and old deleted. Now significant part of document sets are not accessible as user id is changed. The solution could be to change user ID back to old one (available, not assigned) or much more efforts to update all document sets with new user id.
Has anyone delt with this?
