Migration from MI to Intune

Hi there! 

First off, are the new 300 already registered to ZT? If not, this is a little easier. If so, it's still not so difficult. 

You'll need access to the customer portal - https://partner.android.com/zerotouch

I've popped together a guide, it's a little old but thankfully very little has changed on the customer side. You can view that here - https://bayton.org/android/android-enterprise-zero-touch-console-device-guide/

If your devices aren't yet registered, create a configuration, fetch the enrolment token from Intune and input it following this template: https://bayton.org/android/android-enterprise-zero-touch-dpc-extras-collection/#intune. Then set the new config as default, register the devices and they'll pick it up immediately. You can likely even leave it default if you're migrating to Intune permanently 🙂

If the devices are already registered, within the devices page you can use the menu button top-right (3 dots) to upload batch configurations:

Download the example CSV file, input the IMEIs/SNs & data you want to switch, and under the policy ID, put that of your new configuration (you can see this in the configurations page).

If you're got ZT linked to MI at the moment that might be slightly more involved, but this should get you most of the way there 🙂
