How Do I Set Up a Secure Migration Network for Using SMS?

Scenarios

To use SMS, you need to install the Agent on each source server to be migrated. During the migration, each source server must continuously communicate with SMS and the paired target server.

Figure 1 SMS networking

Connecting Source Servers to Huawei Cloud API Gateway

  • The Agent installed on source servers must communicate with Huawei Cloud services IAM, ECS, EVS, IMS, VPC, SMS, OBS, and DNS during the migration. You must ensure that the Agent can call the APIs of these services in the region you are migrating to.
    • IAM and SMS are global-level services. The Agent needs to access their endpoints iam.myhuaweicloud.com and sms.ap-southeast-3.myhuaweicloud.com.
    • ECS, EVS, IMS, VPC, and DNS are region-level services. The Agent needs to access their endpoints in the region you are migrating to.
    • The Agent needs to access OBS endpoints obs.cn-north-1.myhuaweicloud.com and obs.target region code.myhuaweicloud.com.

      Table 1 lists the endpoints of the involved services when you migrate to the region CN South-Guangzhou.

      sms-agent-config-inter.obs.ap-southeast-1.myhuaweicloud.com

      Retain the default values of agent.bucket.endpoint and agent.conf.bucket.endpoint. The URLs of other dependent services depend on the target region.

      SMS uses domain names such as bbs.huaweicloud.com, support.huaweicloud.com, and console.huaweicloud.com to provide migration and consulting services.

  • If the DNS server addresses are not configured on the source server, you need to map each endpoint to its IP address in the local hosts file (C:\Windows\System32\drivers\etc\hosts for Windows and /etc/hosts for Linux).
    The IP addresses can be obtained by pinging the endpoints, as shown in Figure 2.

Connecting Source Servers to Target Servers

  • If you want to migrate over the Internet, you need to purchase an EIP for the target server.
  • If you want to migrate over a private network, you need to purchase a Direct Connect or VPN connection from your source environment to Huawei Cloud.

Opening Required Ports on Target Servers

  • Open the required inbound ports in the security group of each target server.
    • Windows: ports 8899, 8900, and 22
    • Linux: ports 8900 and 22
  • If a network ACL is configured for the subnet you are migrating to, you also need to open the required inbound ports in the ACL.
