Migrate Jabber to Webex App: Use the migration wizard in Control Hub to migrate Cisco Jabber users with Unified CM calling service to the Webex app. After migrating, you can continue to use the existing Cisco Jabber call control options in the Webex app. The Webex app provides users with an easy-to-use experience that allows them to make calls, send messages, share files, schedule meetings, display availability status, and so on.
