This topic describes how to perform a full migration. When you migrate a server from an on-premises IDC or a static application environment to Alibaba Cloud for the first time, you need to perform a full migration. During the full migration, you do not need to stop your current services, but you do need to perform an incremental migration later.

Full migration of a Windows server

Preparations

  1. Verify that the Windows VSS service is enabled.
  2. Check whether you have installed the qemu-agent tool. If so, uninstall it. For more information, see Cloud Migration tool FAQ.

Procedure

  1. Download and install the Cloud Migration tool onto the server to be migrated.
  2. Configure the user_config.json file.

    The user_config.json file contains the following configuration items:

    • The AccessKey information of your Alibaba Cloud account
    • The target zone of migration and the name of the target image
    • (Optional) The size of the target system disk and the configuration of the target data disks
    • The platform and architecture of the source system to be migrated

    For the configuration methods of these items, see Configure the user_config.json file.

  3. (Optional) Configure the directories or files that do not need to be migrated. For more information, see Exclude files or directories from migration.
  4. Run the main program of the Cloud Migration tool.

    Run go2aliyun_client.exe or go2aliyun_gui.exe as the administrator. If the main program is a GUI version, click the Start button to start the migration.

Full migration of a Linux server

The following procedure uses CentOS 7.6 as an example to describe how to perform a full migration of a Linux server.

Preparations

  1. Run the following command to download the Cloud Migration tool to the server to be migrated:
    wget http://p2v-tools.oss-cn-hangzhou.aliyuncs.com/Alibaba_Cloud_Migration_Tool.zip
  2. Run the following command to decompress the Cloud Migration tool:
    unzip Alibaba_Cloud_Migration_Tool.zip


  3. Run the following command to view the hardware architecture of the Linux server to be migrated and decompress the Cloud Migration tool package that applies to this hardware architecture:
    uname -a 
    unzip <the Cloud Migration tool package that applies to the hardware architecture of the Linux system to be migrated>

    In this example, the Linux hardware architecture is x86_64. Therefore, the Cloud Migration tool package that applies to this hardware architecture is go2aliyun_client1.3.2.3_linux_x86_64.zip.



  4. Run the following command to access the directory where the decompressed Cloud Migration tool is located:
    cd <the directory where the decompressed Cloud Migration tool is located>

    In this example, the command is cd go2aliyun_client1.3.2.3_linux_x86_64.

  5. Run the following command to check whether the Linux server meets the migration conditions:
    chmod +x ./Check/client_check
    ./Check/client_check --check

    If all check items are OK, it means that the Linux server meets the migration conditions and you can start the migration.

Procedure

  1. Configure the user_config.json file.

    The user_config.json file contains the following configuration items:

    • The AccessKey information of your Alibaba Cloud account
    • The target zone of migration and the name of the target image
    • (Optional) The size of the target system disk and the configuration of the target data disks
    • The platform and architecture of the source system to be migrated

    For the configuration methods of these items, see Configure the user_config.json file.

  2. (Optional) Configure the directories or files that do not need to be migrated. For more information, see Exclude files or directories from migration.
  3. Run the following command as the root user to grant the execution permission to the main program, and then run this program.
    chmod +x go2aliyun_client
    ./go2aliyun_client
  4. Wait until the main program of the Cloud Migration tool has been completely executed. When the message Go to Aliyun Finished! is displayed, the migration is successfully completed.

What to do next

Go to the image details page in the ECS console to view the result. The OS, applications, and relevant data of your source system are displayed in the ECS console in the format of a custom image.

For the incremental data that is generated during the full migration, you need to perform an Incremental migration.
