Creating a Migration Project

Prerequisites

• You have logged in to the Kunpeng DevKit.
• You have prepared the migration source components. For details, see Preparing Migration Source Components.

Important Notes

• After a migration task is complete on a node, you can create another migration task on the node.
• If a node is occupied by another project, wait until the occupied project is complete and the node is automatically released. Alternatively, delete the project and select another node.
• Components on the same node cannot be migrated to the same target components.
• You can manually add a local node (that is, the current DevKit node) as a migration project node.

Procedure

1. Click System Migration in the navigation tree on the left and then click to go to the New Project tab page.
   Figure 1 New Project
   
2. Set Migration Project Name. A project name is automatically generated by default, which can be changed if needed.

   The name must meet the following requirements:

   • Can contain only letters, digits, and underscores (_).
   • 1 to 64 characters.
3. Under Component Table, configure the components that you want to migrate.
   

   • When configuring the components to be migrated, you can click Save Configuration in the lower left corner to save the current configuration.
   • The estimated migration duration is displayed in real time based on the selected migration content. You can adjust your migration plan accordingly.
   • If the information of some selected components is incomplete, the components are marked with red dots. You need to complete the information before starting the migration.
   • The owning nodes support Kylin V10 SP3 (Arm) and UOS V20 (Arm).
   • Manual adding: You can manually add containerized or non-containerized components.

     1. Click Add.
     2. Enter component information. Table 1 and Table 2 describe the parameters.

        Table 1 Non-containerized components

        Parameter	Description
        Container Migration	Indicates whether to migrate a container.
        Component Belonging	The options are Database, Middleware, and Application.
        Owning Node	Select the nodes to which the component belongs. You can select a maximum of 20 nodes and search for nodes by their IP addresses. If a node is not included on the list, you can click Add Node to add it for the migration project. For details, see Managing Agent.
        Source component
        Source Component Name	Name of the source component to be migrated.
        Version	Source component version. This parameter is available only to databases and middleware.
        Origin of Source Component	Indicates where the source component comes. This parameter is available only to middleware and applications. NOTE: For details about how to package source components (except the RabbitMQ middleware), see Preparing Migration Source Components. Obtain from node server: Obtain the source component package from the specified path on the owning node, scan and analyze it, and generate a migration guide report. If the component belongs to middleware, perform the following steps: Compress the installation directory of the source component to be scanned into a package, for example, a tar.gz package. Replace the example package name and source component directory with the actual ones. 1 tar cvf xxx.tar.gz /xxx/xxx/xxx Log in to the tool through SSH and upload the compressed package to a user-defined directory on the node server. Go to the directory of storing the compressed package. 1 cd User-defined_directory Decompress the source component package. Replace the example package name with the actual one. 1 tar xvf xxx.tar.gz After the decompression is complete, you can run the following command to delete the source component package. 1 rm -f xxx.tar.gz Set the path to the decompressed file as the source component path. Upload source component package: Upload the source component package, scan and analyze it, and generate a migration guide report. If the component belongs to middleware, perform the following steps: Compress the directory of the source component to be scanned into a package, for example, a tar.gz package. Replace the example package name and source component directory with the actual ones. 1 tar cvf xxx.tar.gz /xxx/xxx/xxx Upload the source component package. No source component available: No source component package is provided and no migration analysis is performed. This parameter is available only to middleware.

Download from URL: By default, the target component package is downloaded from the Kunpeng image repository and automatically installed. Obtain from node server: Obtain the target component package from the specified path on the node and start an automatic installation. Access the Kunpeng mirror site to obtain the component installation package. Log in to the tool through SSH and upload the installation package to a user-defined directory on the node server. Specify the installation package path as the target component path. Upload target component package: Click Origin of Target Component in the lower part of the dialog box to obtain the target component package.
        URL	Enter the target URL. NOTE: This parameter is displayed when Origin of Target Component is set to Download from URL.
        Target Component Path	Enter the path to the target component on the owning node. NOTE: This parameter is displayed when Origin of Target Component is set to Obtain from node server.
        Upload Target Component Package	Click Upload to upload the required target component package in .zip, .tar, or .tar.gz format. NOTE: This parameter is displayed when Origin of Target Component is set to Upload Target Component Package.
        Default Deployment Path	The default deployment path of the target component cannot be modified. NOTE: The tool deploys the target component based on the source component path. If the source component path cannot be determined, the default deployment path is used. For the detailed deployment path, see the suggestions on the migration result page.
        Commercial Certificate	Click Upload to upload the required commercial certificate.

     Docker Compose is a tool for defining and running multi-container applications. It is the key to unlocking a streamlined and efficient development and deployment experience. Compose simplifies the control of your entire application stack, making it easy to manage services, networks, and volumes in a single, comprehensible YAML configuration file.

     2. Upload the Docker Compose file and select the owning node.
     3. Click Analyze.
     4. After importing the parsed components, click Edit in the Operation column to complete the configuration. For details, see Table 3.
