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

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

• The Agent installed on source servers must communicate with 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 where you are migrating to. You can check the URLs of these services in the SMS-Agent/config/cloud-region.json file.
• 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 (/etc/hosts for Linux). The IP addresses can be obtained by pinging the endpoints.

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

• Linux target servers: Open ports 8900 and 22.
• If a network ACL is configured for the subnet where the target server is located, open the required inbound ports in the network ACL.
