What's not changing

Once you migrate to Cloud Sync, your hybrid authentication features that enable on‑premises credentials to be used for accessing cloud resources will continue to be available after migration on the Connect Sync config wizard.

Start preparing today

We recommend that you take steps to begin your migration. You can begin familiarizing yourself with Entra Cloud Sync and review our dedicated resources to ensure a smooth transition:

• Cloud Sync deep dive – how it works
• Step-by-step migration guidance
• Migration scenarios:

• Migrate to Microsoft Entra Cloud Sync for a synced Active Directory forest
• Migrate Microsoft Entra Connect Sync Group Writeback v2 to Microsoft Entra Cloud Sync
• Microsoft Entra Cloud Sync vs. Microsoft Entra Connect Sync feature comparison

Microsoft Entra supports Source of Authority (SOA) capabilities that allow you to shift user and group management to the cloud while continuing to operate existing Connect Sync deployments. These capabilities can help simplify environments, reduce long‑term dependency on on‑prem infrastructure, and improve readiness for future transitions. If this aligns with your identity strategy, the following resources may be helpful:

• IT Architect Guidance for SOA planning: https://aka.ms/SOAITArchitectsGuidance
• User SOA: Manage users directly in Entra ID while maintaining hybrid coexistence
• Group SOA: Cloud‑managed groups with on‑premises impact where required

This is not a prerequisite to move to Cloud Sync, but provides an opportunity to prepare at your own pace.
