Associating Source Servers with Target Servers

You can associate source servers with existing servers on Huawei Cloud. Then your workloads can be migrated to these Huawei Cloud servers.

For source servers with target servers associated, there is no need to assess them before you create workflows to execute migrations.

Prerequisites

You have finished resource discovery and collection by referring to Simple Project.

Notes

A target server must meet the following requirements:

  • The target server must be stopped.
  • During the migration, disks on the target server are formatted and re-partitioned based on the source disk settings for receiving data migrated from the source server.
  • To migrate over the Internet, the target server must be able to access the Internet.
  • The target server must be in the same region as the application to which the source server is added.

Procedure

  1. Sign in to the MgC console.
  2. In the navigation pane on the left, choose Design > Migration Solutions. Select a migration project in the upper left corner of the page.
  3. Click View in the Target Configuration card.
  4. On the displayed Servers tab, locate a source server and click Associate in the Target Association column.
  5. In the displayed dialog box, select the region of the application and select a project. You can select a target server based on the disk usage of the source server. This allows you to choose a target server with a smaller disk capacity or fewer disks than the source server, reducing disk capacity, optimizing resource utilization, and avoiding unnecessary costs.

    • Disk downsizing is only available for Linux, and the decreased sizes must be larger than the used sizes of the source disks.
    • In the cross-AZ migration scenario, only disk upsizing is supported. Even if you choose to downsize disks here, the settings will not be applied, and the system will create target disks as large as source disks.

  6. Click OK. After the association is complete, Associated appears in the Target Association column. You can click Details to view the specifications of the associated target server. The system will automatically check whether the associated target server has downsized disks compared with the source server. If it does, Yes will be displayed in the Disk Downsized column. If it does not, No will be displayed.

Dissociating a Source Server from the Target Server

  1. On the Servers tab, locate the source server and click Dissociate from Target in the Operation column.
  2. In the displayed dialog box, click Yes. Please note that this operation cannot be undone.
