Hi, can you please clarify which type of Classic Policies need to be migrated?
All or only one targeted to Intune related apps or this requires compliance like "[Office 365 Exchange Online] Device policy"?
Because Defender for Endpoint (MDE/MDATP) and other security connectors seems still rely on legacy CA policy created when connector created like "[Windows Defender ATP] Device policy" which when disabled and deleted broke the connection itself.
For example one of the oldest tenants have these policies enabled:
- [Office 365 Exchange Online] Device policy
- [GraphAggregatorService] Device policy
- [Office 365 SharePoint Online] Device policy
- [Outlook Service for OneDrive] Device policy
- [Outlook Service for Exchange] Device policy
- [Windows Defender ATP] Device policy
