As for many services or products, you can find an adoption pack to help you communicating with your end-users when deploying a new version or migrating to a new service.
Now, you also have the same for Microsoft Intune.
The adoption pack for Intune available here https://aka.ms/IntuneAdoptionKit contains the usual communication templates (emails, deployment guide…)
As you may notice the version of this pack is matching the current Intune version (1906); which means it may be updated in the future following the Intune upgrade and when new services/features are added.
Enjoy
