Hi @HASSAN BIN NASIR DAR , the best resources to follow are our Learn documents about the process: https://learn.microsoft.com/en-us/entra/architecture/road-to-the-cloud-migrate

Please review these documents and let me know if you have any specific questions about the process.

This is a high-level overview:

1. Assess the Current Environment: Evaluate the existing on-premise Active Directory environment, including the number of users, groups, and devices. Identify any dependencies or applications that rely on the on-premise AD.
2. Plan the Migration: Develop a detailed migration plan that includes timelines, resources, and potential risks. Ensure that all stakeholders are informed and involved in the planning process.
3. Prepare Azure AD: Set up an Azure AD tenant if one does not already exist. Configure the necessary Azure AD services, such as Azure AD Connect, to synchronize on-premise AD with Azure AD.
4. Synchronize Identities: Use Azure AD Connect to synchronize on-premise AD identities with Azure AD. This step ensures that all user accounts, groups, and other directory objects are replicated in Azure AD.
5. Migrate Applications: Identify and migrate any applications that rely on the on-premise AD for authentication and authorization. Update the applications to use Azure AD for these services.
6. Test the Migration: Conduct thorough testing to ensure that all directory objects and applications are functioning correctly in the Azure AD environment. Address any issues that arise during testing.
7. Decommission On-Premise AD: Once the migration is complete and all tests are successful, decommission the on-premise Active Directory. This step involves shutting down the on-premise AD servers and removing any remaining dependencies.
8. Monitor and Maintain: After the migration, continuously monitor the Azure AD environment to ensure it is functioning correctly. Implement any necessary maintenance and updates to keep the environment secure and efficient.
