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.

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.
