Entra Connect to Cloud Sync: Migrate Now

Key insights

• Microsoft Entra Cloud Sync vs Entra Connect: The demo explains that Cloud Sync is a cloud-managed hybrid identity sync service that syncs users, groups, and contacts from on-premises Active Directory to Entra ID.
  It is positioned as a simpler, lower-maintenance alternative to running the full on-premises sync engine.
• Migration wizard and migration tool: The video walks through Microsoft’s guided migration workflow.
  The tool signs in with a Hybrid Identity Administrator role, checks blocking conditions, transfers supported settings, and validates the new Cloud Sync setup.
• Key advantages: Cloud-based management reduces server maintenance.
  Phased rollout and pilot testing let you move objects in batches and confirm success before full cutover.
• Basic migration flow: Review guidance, pick a pilot OU or test forest, install the Cloud Sync agent, verify provisioning and group membership, then move remaining objects in phases.
  Only stop Entra Connect after you validate Cloud Sync for the scoped objects.
• Decision guide and limits: Microsoft provides clear criteria for who can migrate now and who should wait.
  Note the published group-size guideline of 50,000 members and the need to confirm supported features before moving.
• What to watch for: Check prerequisites, confirm feature dependencies, and validate memberships and manager relationships during pilots.
  Keep the old sync server disabled for a validation window and only decommission it after you confirm the migration succeeded.

Overview of the video

In a clear, step-by-step YouTube walkthrough, Andy Malone [MVP] demonstrates Microsoft's new migration path from Entra Connect to Entra Cloud Sync. The video focuses on the migration wizard and shows how administrators can move synchronization responsibilities from an on-premises sync engine to a cloud-managed agent. As Malone explains the staged approach, he emphasizes assessment, piloting, and phased cutover so teams can limit risk during the transition.

Furthermore, the presenter frames the migration as practical for organizations that want less server maintenance while maintaining hybrid identity. He notes that Microsoft now offers explicit decision guidance and a transfer workflow to avoid rebuilding sync configuration by hand. Consequently, the video serves as both a demo and a primer for IT teams weighing the move.

Demonstration highlights

Malone walks viewers through the migration wizard, showing how to sign in with the Hybrid Identity Administrator role, review blocking conditions, and transfer supported settings to Entra Cloud Sync. He then configures the cloud agent and validates provisioning for a pilot OU, stressing verification steps such as group membership checks and manager relationships. Throughout the demo he pauses to explain screen prompts and expected outcomes, which helps administrators know what to look for in their environments.

In addition, the video demonstrates how to leave the old sync server disabled but available during validation so teams can compare results before decommissioning. Malone also highlights the recommended phased rollout by moving objects in batches and confirming integrity after each step. Thus, viewers get practical runbook-style guidance as well as a live example of the actual tool behavior.

Finally, Malone points out scenarios where the migration wizard can transfer configuration automatically and where manual steps remain necessary. He explains that the tool streamlines many common cases, but it does not hide the need for planning or pilot testing. As a result, administrators should expect some hands-on verification during and after migration.

Advantages and tradeoffs

One clear advantage shown in the video is the shift to cloud-managed synchronization, which reduces the need for a dedicated on-premises sync server and related maintenance. This simplifies operations and centralizes management in the Entra admin center, which many teams prefer for modern workflows. However, Malone also explains the tradeoff: not every Entra Connect feature maps directly to Cloud Sync, so some organizations must delay migration or adopt hybrid approaches.

Moreover, Microsoft’s guidance sets practical limits, such as advising caution when groups exceed certain sizes, which affects large-member groups and complex scopes. Malone underscores that feature compatibility and object scope drive the decision to move now or later, making careful assessment essential. Therefore, the benefit of reduced server maintenance must be balanced against potential missing features or manual rework.

Another tradeoff relates to risk management: the video advocates for pilot-first testing and phased cutover, which reduces disruption but extends rollout time. While this approach increases safety, it also demands more coordination and temporary coexistence of tools. Consequently, teams should budget time and personnel for validation windows rather than treating the migration as a single downtime event.

Troubleshooting and common challenges

Malone dedicates part of the video to troubleshooting, showing how to handle blocking conditions and validating group and membership integrity after export. He demonstrates typical fixes such as re-running validation checks, reviewing agent logs, and adjusting scope filters when objects do not appear as expected. These examples help administrators anticipate problems and prepare corrective steps before they occur in production.

He also highlights tricky cases such as multi-forest environments, manager relationships, and very large groups where behavior can differ from a simple pilot. In those scenarios, Malone recommends staged testing and consultation of the decision guide to determine whether manual intervention or a mixed approach is required. As a result, teams can more realistically scope effort and schedule migration windows.

Recommended migration approach

Based on the demo, the sensible path starts with assessing feature dependencies and identifying a pilot OU or test forest to validate the transfer process. Malone suggests installing the Cloud Sync agent, configuring a controlled pilot, and then verifying provisioning and group membership thoroughly before extending scope. This phased strategy reduces surprises and gives teams the chance to roll back by re-enabling the old sync while keeping it offline for validation.

Finally, he urges administrators to keep the old server disabled but not decommissioned until they are confident that Cloud Sync manages the intended objects correctly. By following Microsoft’s staged guidance and Malone’s troubleshooting tips, organizations can balance speed and safety when moving to Entra Cloud Sync. In short, the video offers a practical, realistic playbook that helps teams plan the migration with fewer surprises and clearer validation steps.
