Migrating from Microsoft Entra Connect Sync?
If you currently use Microsoft Entra Connect Sync, choose your migration path in this order:
- Review the migration decision guide to determine whether Cloud Sync supports your organization's requirements.
- If your organization and active Connect Sync installation meet the guided migration-tool requirements, use the guided tool.
- If the guided tool doesn't support your scenario, use a documented manual migration procedure only when one is available. Otherwise, continue using Connect Sync. Review the migration overview and manual migration tutorial to identify the applicable guidance.
For common questions, see the migration FAQ. If you require device synchronization, review Device Sync separately from guided-tool eligibility.
