Using Custom Agent Images

You can customize agent images by referring to Creating a Windows Agent Image and Creating a Linux Agent Image. Then you can use these custom agent images for migration by modifying the SMS Agent configuration file.

SMS only provides standard, security-hardened agent images for testing use. You need to use your custom agent images for migration.

You are advised to use your custom agent images for migration of sensitive data. Before the migration, you need to scan and evaluate security risks in your agent images. Huawei Cloud can provide help for you. You are responsible for possible migration failures and data losses caused by the security risks identified in your agent images.
The agent images provided by SMS are only for migration testing. You are not advised to use them for other purposes.
In your custom agent images created using SMS agent images, do not change the IP address 169.254.XX.XX contained in the scripts. The IP address is used by ECS to access the metadata service.
