Server Migration Center:Manage the SMC client

Get the SMC client

• If you import a migration source using the console or the command line, the SMC client is automatically downloaded and installed on the source server.

• If you choose to import the migration source using the client, you need to manually download the SMC client compressed package for the source system's operating system, as shown in the following table.

  Operating system	Architecture	SMC client compression package
  Windows	x86_64	Windows 64-bit General-purpose Edition
  	x86_32	Windows 32-bit General-purpose Edition
  Linux	x86_64	Linux 64-bit General-purpose Edition
  		Linux 64-bit high-kernel edition (supports Linux systems with kernel version 5.x or later)
  	x86_32	Linux 32-bit General-purpose Edition
  	ARM	Linux 64-bit ARM Edition

View the SMC client

• If you import a migration source using the console or the command line:

  • For a Windows source server, the default installation directory of the SMC client is C:\smc.

  • For a Linux source server, the default installation directory of the SMC client is /smc.

• If you import a migration source by manually downloading the client, the SMC installation directory is the directory where you extracted the compressed package.

Start and stop the SMC client

The SMC daemon service is installed when you import a migration source. You can start and stop the SMC client by starting and stopping the SMC daemon service.

The SMC daemon service is not supported on 32-bit Windows systems. Run go2aliyun_client.exe instead.

• Linux

  The installation path of the SMC daemon process is /smc/smc_daemon. Run the /smc/smc_daemon --status command to check the status of the SMC daemon service. The output indicates the status: RUNNING means the service is running, STOPPED means the service is stopped, and UNINSTALLED means the service is not installed.

  • Start the SMC client: Run the following command to start the SMC daemon service. This action also starts the SMC client program.

    /smc/smc_daemon --start

  • Stop the SMC client: Run the following command to stop the SMC daemon service. This action also stops the SMC client program.

    /smc/smc_daemon --stop

• Windows

  The installation path of the SMC daemon process is C:\smc\smc_daemon.exe. In PowerShell, run the C:\smc\smc_daemon.exe --status command to check the status of the SMC daemon service. The output indicates the status: RUNNING means the service is running, STOPPED means the service is stopped, and UNINSTALLED means the service is not installed.

  • Start the SMC client: Run the following command to start the SMC daemon service. This action also starts the SMC client program.

    C:\smc\smc_daemon.exe --start

  • Stop the SMC client: Run the following command to stop the SMC daemon service. This action also stops the SMC client program.

    C:\smc\smc_daemon.exe --stop

Uninstall the SMC client

After you complete the migration, follow these steps to uninstall the SMC client.

• Linux

  1. Stop and delete the SMC daemon service.

     /smc/smc_daemon --stop
     /smc/smc_daemon --uninstall

  2. Clear the remaining cached data.

     ./Check/client_check --ssclear smcss

  3. Delete the SMC client directory.

     The following example uses the default installation path of the SMC client directory.

     rm -rf /smc

• Windows

  1. In PowerShell, run the following commands to stop and delete the SMC daemon service.

     C:\smc\smc_daemon.exe --stop
     C:\smc\smc_daemon.exe --uninstall

  2. Delete the SMC installation directory C:\smc.

FAQ

• How do I check the running status of the SMC client process?

  Linux

  Replace <installation_directory_name> with the actual directory name. The following example uses the default installation path of the SMC client directory.

  tail -f /smc/<installation_directory_name>/Logs/go2aliyun_client.out

  For example, if the installation directory is go2aliyun_client3.1.0_new_linux_x86_64, run tail -f /smc/go2aliyun_client3.1.0_new_linux_x86_64/Logs/go2aliyun_client.out.

  Windows

  In PowerShell, run the following command to check whether the client is running as expected.

  Replace <installation_directory_name> and <log_name> with the actual names. The following example uses the default installation path of the SMC client directory.

  Get-Content C:\smc\<installation_directory_name>\Logs\<log_name> -Wait -Tail 50

  For example, if the installation directory is go2aliyun_client3.1.0_windows_x86_64 and the log name is go2aliyun_client_20251010.log, run Get-Content C:\smc\go2aliyun_client3.1.0_windows_x86_64\Logs\go2aliyun_client_20251010.log -Wait -Tail 50.

  • Normal operation: The output contains Import Source Server [s-bp18x8751kgz2oyh****] Successfully!

    • If no migration task is associated, the status of the migration source changes to Online.

    • If a migration task is associated, the status of the migration source changes to Migrating. If the migration task is in the Error state, find the task and click Retry Task in the Actions column to resume the migration task.

  • Error: If an error occurs, identify the cause based on the error code and try again. For more information, see Troubleshooting.

    

• How do I start and stop the SMC client on systems that do not support the SMC daemon service?

  The SMC daemon service is not supported on 32-bit Windows systems. Follow these instructions to start and stop the SMC client. Replace <installation_directory_name> with the actual directory name.

  • To start the SMC client program, run the command C:\smc\<installation_directory_name>\go2aliyun_client.exe.

    For example, if the installation directory is go2aliyun_client3.1.0_windows_x86_64, run C:\smc\go2aliyun_client3.1.0_windows_x86_64\go2aliyun_client.exe.

  • To stop the SMC client program, run the command C:\smc\<installation_directory_name>\go2aliyun_client.exe --abort.

    For example, if the installation directory is go2aliyun_client3.1.0_windows_x86_64, run C:\smc\go2aliyun_client3.1.0_windows_x86_64\go2aliyun_client.exe --abort.
