Migrating Windows Server from 'Hybrid Azure AD Join' to 'Entra ID Join (Cloud-Only)'

Hi everyone,

I need help with a scenario where I’m looking to move a server ( non DC ) from Microsoft Entra Hybrid Joined to cloud only (Entra ID) Joined only. The goal is to stop relying on the on-premises AD domain and make the server authenticate only through cloud-based accounts (Azure AD accounts). 

I’d appreciate any guidance, documentation or best practices on how to properly handle this migration while ensuring minimal disruption. 

Has anyone done this transition before?
What steps and considerations should I be aware of in terms of network configuration, Cost.... etc?

Thanks in advance for your help!
