If you are working on two or more projects, you can switch between them in your current session in Experience Manager.
Verify that you have saved any work that you want to keep in the current project.
Click the project tile of the Workbench toolbar.
The project popover appears listing your current project and all of the other active projects associated with your site that have not been published, yet. Projects that have unresolved conflicts in them are preceded by the Conflict icon.
The name of the project creator follows the project name.
You can switch between as many projects as you like. The next time that you log in to Workbench, Experience Manager opens with the last project in which you were working.
