Question

Your organization uses Microsoft Entra Connect Sync running on a single server named SYNC01 to synchronize on-premises Active Directory objects to Microsoft Entra ID. To reduce downtime risk, you deploy a second server named SYNC02 with Entra Connect installed in staging mode. During a planned outage of SYNC01, you need SYNC02 to take over synchronization to Microsoft Entra ID with the least administrative effort and no data loss. What should you do?

Accepted Answer

On SYNC02, run the Entra Connect wizard, disable staging mode, and let it become the active sync server.

Answer

Uninstall Entra Connect from SYNC01, then reinstall and reconfigure Entra Connect on SYNC02 from scratch.

Answer

Enable Entra Cloud Sync on SYNC02 to replace the Connect Sync agent on SYNC01.

Answer

In the Microsoft Entra admin center, switch the synchronization source to SYNC02 under Connect Sync settings.
