   The name must meet the following requirements:

   • Can contain only letters, digits, and underscores (_).
   • 1 to 64 characters.
3. Set Migration Scenario to Manual migration.
4. Select migration project nodes. You can select a maximum of 20 nodes and search for nodes by their IP addresses or names. 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.
5. Click Configure Migration Components. Under Component Table, configure the components that you want to migrate.
   Figure 2 Configure Migration Components
   
   • 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.

     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.

     1. Click Import Using Docker Compose.
     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.

   1. Click Upload and drag the source packages to the upload area. Alternatively, you can click Add File to select source packages and click Upload.
   2. Optional: If you select Database in Component Table and need to scan an SQL source package, you are advised to configure the data definition language (DDL) file. For details about how to obtain a DDL file, see Exporting a DDL File.
   

   • The supported source package formats are tar, tar.bz, tar.bz2, tar.gz, tar.xz, tbz, tbz2, tgz, txz, and zip. You can upload multiple source packages at the same time. Each of the source packages must be less than or equal to 2048 MB.
   • For Dockerfile and Docker Compose files, the tool identifies the statements that do not support the Arm architecture and provides modification suggestions. For details about the file matching rules, see Dockerfile and Docker Compose Trustlist and Replacement List.
   • The tool detects the drivers, dependencies, Druid, and JPA configurations in the source code, and provides Quick Fix suggestions.
