Hello
Thank you for your question and reaching out. I can understand you are having query related to Azure and On-Prem AD.
Azure Active Directory is the cloud version of the Windows Server Active Directory. Well, that’s not strictly true. Technically speaking, Azure AD is more than a directory or domain controller, and it doesn’t have the same features as Active Directory. As an identity and access management solution, Azure AD has more capabilities, but they are different from those of on-prem AD.
In short, there is no direct migration path from on-prem AD to Azure AD. However, you can combine the two to get the best of both worlds. You can synchronize your on-prem directories with Azure AD and still preserve your GPOs and OUs. This is possible through the Azure AD Connect Sync Server that enables Azure AD to authenticate on-prem users.
