 #### Global projects
 
 The root (global) namespace for projects is deprecated.
-So you need to move all your global projects under groups or users manually before update or they will be automatically moved to the project owner namespace during the update. When a project is moved all its members will receive an email with instructions how to update their git remote url. Please make sure you disable ssending email when you do a test of the upgrade.
