In SCCM 1610 we got a new feature for changing MDM Authority from the SCCM console.
Things are changing fast in Intune standalone – so if you chose a Intune Hybrid with SCCM don’t worry – it is a decision that can be changed that can be changed.
Your can do it your self from the SCCM console.
It still requires a call to Microsoft Intune support to get your tenant enabled for this feature.
Please read the new “Choose between Microsoft Intune standalone and hybrid mobile device management with System Center Configuration Manager” from Microsoft when you are designing your Intune MDM solutions.
How are you change MDM Authority to Microsoft Intune:
Go into your SCCM Console
Administration -> Cloud Services -> Intune subscription
Click Delete
Select Change MDM Authority to Microsoft Intune
Click Next
Click Yes
Remember that you need to recreate every thing in Intune standalone – policies and applications.
But you don’t have to reenroll your users devices – so your users don’t have to get involved when you are making a backend change in your environment.
