Hi SuryBoom ,
Here are some answers for your questions:
- The old setup will continue to work. In the current version, there are no differences between the old setup and what is available as part of GA. We are aiming to release a new version into Public Preview in the month of December. If you would like to use the new setup then, the recommendation would be to create and use the new setup and abandon or delete the olde setup.
- For device looking to migrate, please remove the device from the current/old setup group, give it a few hours to sync from Intune, and then add it to the groups used in the new setup.
- Intune 2309 has the contents for our feature.
- We are working to add Windows Hello for Business support and we are aiming to release this in Public Preview in the month of December.
Thanks,
Derek
