Remove On-prem servers from hybrid environment

[AGW3RT]

Hi,

I am at the last stage of moving from a hybrid environment to cloud only.  All devices are managed with InTune, and our on-prem servers only manage users and groups which are synced through AAD Connect (I have only the DCs and ADFS servers left on-prem).

How do I go about removing my internal infrastructure and managing everything cloud-only?

Any advice gratefully received

@AGW3RT Just turn off AD connect syncing Turn off directory synchronization for Microsoft 365 - Microsoft 365 Enterprise | Microsoft Docs

That will cause all objects to become cloud source/only objects in Azure AD. I would also not recommend to remove everything right a way, keep the servers for a few weeks or so just to make sure you didn't break some critical system that still was relying on AD.

Also make sure your domains are cloud managed and not federated as you mentioned ADFS.

Thanks for that @brlgen , so after this I just run Convert-MsolDomainToStandard?
