If you synced classrooms through Clever or ClassLink but shared the wrong sections, or you want to remove older classrooms and add new ones, de-integrating is a good first step. De-integrating archives **all** synced classrooms; you then change sharing rules and re-integrate to pull the changes in. ## De-integrate the Account Go to [manage.goguardian.com](https://manage.goguardian.com/), select the **Integrations** tab, and click the trash icon under the service used to sync classrooms. De-integrating automatically archives all classrooms for teachers.

## Change Classroom Sharing Permissions In your rostering provider's sharing permissions, remove sections to archive them and add new sections to share them with GoGuardian. See your provider's documentation for setting up sharing rules in [Clever](https://support.clever.com/) or ClassLink. ## Re-Integrate Re-integrating after changing sharing permissions excludes the old or unwanted classrooms. Click **Sync** in the Clever or ClassLink panel under the **Integrations** tab in Org Management to begin. New classrooms appear as "Created" in the Teacher Audit Log. Re-integrated classes move from the **Archived** tab to **Pending** in teachers' dashboards and show as "Updated" in the Teacher Audit Log.
