A company recently acquired two smaller firms, each running its own independent Active Directory forest with no trust relationships between them. The parent company already synchronizes its primary forest to Microsoft Entra ID using Microsoft Entra Connect Sync with a single server. The IT team must integrate identities from the two newly acquired forests into the existing Entra tenant as quickly as possible, minimize on-premises infrastructure footprint, and support lightweight, agent-based deployment that is resilient to server outages. Which identity synchronization approach should you recommend for the two acquired forests?
