Can I change a Resource into a Web User? Or can I move a User from one Type to another? Can I change Object from Resource to Staff?

You cannot change a Resource into a User/Web User. 

• Instead set the Resource INACTIVE and it will no longer be available in the Object Browser. 
• It will also disappear from Hourline Groupings that are "dynamic" such as Groupings made from Class or Category. 
• In other groupings please manually "remove" the Resource from the view.
• Create a new User for the person and book that Object from now on.
• Additionally you can add "Inactive" to the name of the Resource to make sure it's not being used going further.
