Server Migration Center:Manage the SMC client

Get the SMC client

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

• If you import a migration source by using the client, download the SMC client package for your operating system from the table below.

  Operating system	Architecture	SMC client package
  Windows	x86_64	Windows 64-bit (general)
  	x86_32	Windows 32-bit (general)
  Linux	x86_64	Linux 64-bit (general)
  		Linux 64-bit (high-kernel, supports Linux 5.x kernel versions)
  	x86_32	Linux 32-bit (general)
  	ARM	Linux 64-bit (ARM)

View the SMC client

• If you imported a migration source from the console or command line:

  • On Windows, the default installation directory is C:\smc.

  • On Linux, the default installation directory is /smc.

• If you downloaded the client manually, the installation directory is where you decompressed the package.

Start and stop the SMC client

The SMC daemon service is installed when you import a migration source. Start or stop the client by controlling the daemon service.

32-bit Windows does not support the daemon service. Run go2aliyun_client.exe directly.

• Linux

  The daemon is located at /smc/smc_daemon. Run /smc/smc_daemon --status to check the service status. Possible outputs: RUNNING, STOPPED, or UNINSTALLED.

  • Start the SMC client:

    /smc/smc_daemon --start

  • Stop the SMC client:

    /smc/smc_daemon --stop

• Windows

  The daemon is located at C:\smc\smc_daemon.exe. In PowerShell, run C:\smc\smc_daemon.exe --status to check the service status. Possible outputs: RUNNING, STOPPED, or UNINSTALLED.

  • Start the SMC client:

    C:\smc\smc_daemon.exe --start

  • Stop the SMC client:

    C:\smc\smc_daemon.exe --stop

Uninstall the SMC client

After a client-based migration, you can uninstall the SMC client.

• Linux

  1. Stop and remove the SMC daemon service.

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

  2. Clear residual cached data.

     ./Check/client_check --ssclear smcss

  3. Delete the SMC client directory.

     This example uses the default path.

     rm -rf /smc

• Windows

  1. In PowerShell, stop and remove the daemon service.

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

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

FAQ

• Check the SMC client process status

  Linux

  Replace <installation_directory_name> with your directory name. This example uses the default path.

  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:

  Replace <installation_directory_name> and <log_name> with your values. This example uses the default path.

  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.

• Start and stop the client manually

  32-bit Windows does not support the daemon service. Start and stop the client manually. Replace <installation_directory_name> with the actual directory name.

  • To start the SMC client, run 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, run 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.
