Use the Resource Inspection Feature

Create a resource inspection plan

Log on to the CMH console. In the left-side navigation pane, choose Migration capability > Resource inspection. On the Resource inspection page, click Create resource inspection.

On the Create resource inspection page, configure the Plan Name and Remarks parameters in the Cutover Resource Association step. Configure the Associated Resources parameter based on your business scenarios. CMH supports three association methods.

1. Associate the target resources of a migration plan

Performs inspection on the resources of a migration plan that is created in the CMH console.

2. Associate resources based on conditions

Performs inspection on resources in the specified regions and to which the specified tags are added.

3. Select Instance Directly

Performs inspection on the specified instances.

Note: You can select all association methods to perform inspection. In this case, the system performs inspection on all resources that meet the conditions specified by the association methods.

After you complete the configurations, click Next.

In the Migration Task Association step, select forward Data Transmission Service (DTS) tasks. This allows you to create multiple reverse DTS tasks at a time in the cutover phase. For more information, see Create reverse DTS tasks. The Migration Task Association step is optional. If you do not need to create reverse DTS tasks, you can directly click Yes to create the resource inspection plan.
