When using Apple Configurator, you can assign an existing supervision identity to be used with devices you place into supervision. To do so, first open Apple Configurator and click on Organizations.
From Organizations, click on the plus sign (“+”).
From the Create an Organization screen, click Next.
When prompted to provide information about your organization, provide the name, phone, email, and/or address of the organization.
If you are importing an identity, select “Choose an existing supervision identity” and click on Next.
When prompted, click Choose to select the identity to use (e.g. exported from another instance of Apple Configurator or from Profile Manager).
Click Choose when you’ve highlighted the appropriate certificate.
Click Done.
