Viewing migration overview

After you log in to the controller, the Overview page opens by default. It provides a real-time summary of the global migration status and system running status. Data is automatically refreshed every 30 seconds.

Task overview

The horizontal bar at the top of the page displays global migration statistics:

Parameter	Description
Manual attention	Displays three categories: need troubleshooting (Migration failed and needs intervention), ready for cutover (Migration waiting for cutover), and archivable (Migration completed and awaits for archiving).
Active tasks	Displays the total number of tasks that are currently in data transfer (full or incremental) and the current global transfer rate in MiB/s.

Migration status dashboard

The left side in the middle of the page displays the running status of migration plans in two groups by priority:

• Running properly: Includes plans that are running normally or waiting for manual cutover.
• Needs attention: Includes plans with failed tasks.

Each plan summary displays the plan name, status label, and number of migrated virtual machines compared to total virtual machines. Click View all plans → to navigate to the migration plan list page.

System health and capacity

The right side in the middle of the page displays the current status of system infrastructure:

• WORKER STATUS: Displays the number of online workers compared to total workers, and whether all current worker nodes are online.
• CONCURRENCY AND QUEUE: Displays the used concurrency compared to maximum concurrency and number of queued tasks for full migration, incremental sync, and cutover operations.
• BANDWIDTH USAGE: Displays the current transfer bandwidth of each worker node by row in MiB/s, differentiates the bandwidth contribution of full migration, incremental sync, as well as cutover, and displays the global bandwidth summary at the bottom.
• SITE STATUS: Displays the number of online sites compared to total sites; the number of unreachable sites; the number of active source sites; the number of active target sites; the number of sites to be synchronized compared to sites failed to be synchronized; and statistics for VMware vCenter sites and Arcfra VM service cluster sites.

Historical task overview

The bottom of the page displays historical migration summary data, including the total number of migrated virtual machines, cumulative migrated data, the number of completed plans, the number of canceled plans, and the number of archived plans.
