Preparations

Creating a Migration Project

Migration projects allow you to group, isolate, and manage migration resources. For details, see Managing Migration Projects.

Preparing Edge

To verify big data consistency, you need to install Edge for Linux in your source environment. For details, see Installing Edge for Linux. After Edge is installed, connect Edge to MgC. For details, see Connecting the Edge Device to MgC.

Edge does not support automatic restart. Do not restart Edge during task execution, or tasks will fail.

2. In the navigation pane on the left, choose Migrate > Big Data Verification. In the upper left corner of the page, choose the migration project you created from the project drop-down list
3. Click Select Edge Device.
4. In the displayed dialog box, select the Edge device you connected to MgC from the drop-down list.
   • If an Edge device is Online and Enabled, the device has been used for big data verification in a project. You can click Confirm to continue using the tool.
   • If an Edge device is Online and Disabled, the device has not been used for big data verification in any project, and you can click Enable to use this device for big data verification.
   • If an Edge device is Offline and Deleted, the device has been deleted, and it cannot be used for big data verification. However, if this device has been used for big data verification before being deleted, you can select it and click View to view the verification tasks and results.
   • If an Edge device is Offline and Disabled, the device cannot be used for big data verification, and all operation buttons are disabled even if you select it and click View.
