Switch to the SMS-Agent directory on the source server.
```
cd SMS-Agent
```
If you do not need to use an HTTPS proxy, go to 7.

If you do not need to use an HTTPS proxy, go to 8.
- If your source server cannot access Huawei Cloud over the Internet, a proxy server can help you. You need to configure a proxy server by yourself.
- The proxy is used for registering the source server with SMS when a Direct Connect or VPN connection is used. It is not used for data migration.
(Optional) Configure the HTTP/HTTPS proxy for the Agent.
1. Go to the config directory.
```
cd SMS-Agent/agent/config
```
2. Open and edit the auth.cfg file. Do not edit the auth.cfg file unless you need to use an HTTP/HTTPS proxy.
```
vi auth.cfg
```
  The values shown here are for reference only.
```
[proxy-config]
enable = true
proxy_addr = https://your-proxy-addr.com
proxy_port = 3128
proxy_user = root
use_password = true
```
  - enable: To use a proxy, set it to true.
  - proxy_addr: Replace your-proxy-addr with the IP address of the proxy server, not that of the target server. Use the protocol configured for the proxy. HTTPS is recommended.
  - proxy_user: Enter the username required for the proxy. If no username is required, leave it blank.
  - use_password: If a password is required for the proxy, set it to true. If no password is required, set it to false.
3. Save the auth.cfg file and exit.
```
:wq
```
Start the Agent.
```
./startup.sh
```
Carefully review what information will be collected by the Agent, enter y, and press Enter.

Figure 1 Entering y
Enter the AK/SK pair of the Huawei Cloud account and the SMS domain name for the region you are migrating to. You can obtain the SMS domain name on the Agents page of the SMS console, as shown in Figure 3.

Figure 2 Entering the AK/SK pair

Figure 3 Obtaining the SMS domain name

If the EPS service has been enabled for the Huawei Cloud account, after you entered the AK/SK pair, the Agent will list all enterprise projects the account is allowed to access. You can select the enterprise you would like to migrate the source server to. This enables you to isolate permissions, resources, and finance during the migration. For details, see Migrating Servers into an Enterprise Project.

When the following information is displayed, the Agent has been started up and will start reporting source server information to SMS. You can go to the Servers page on the SMS console to view the record of the source server.
