4.5. Creating custom migration targets

Architects or users with admin permissions can create and maintain custom rulesets associated with custom migration targets. Architects can upload custom rule files and assign them to various custom migration targets. The custom migration targets can then be selected in the analysis configuration wizard.

By using ready-made custom migration targets, you can avoid configuring custom rules for each analysis run. This simplifies analysis configuration and execution for non-admin users or third-party developers.

Prerequisites

  • You are logged in as a user with admin permissions.

Procedure

  1. In the Administration view, click Custom migration targets.
  2. Click Create new.
  3. Enter the name and description of the target.
  4. In the Image section, upload an image file for the target’s icon. The file can be in either the PNG or JPEG format, up to 1 MB. If you do not upload any file, a default icon is used.

  5. In the Custom rules section, select either Upload manually or Retrieve from a repository:

    • If you selected Upload manually, upload or drag and drop the required rule files from your local drive.

    • If you selected Retrieve from a repository, complete the following steps:

      1. Choose Git or Subversion.
      2. Enter the Source repository, Branch, and Root path fields.
      3. If the repository requires credentials, enter these credentials in the Associated credentials field.

  6. Click Create.

    The new migration target appears on the Custom migration targets page. It can now be used by non-admin users in the Migration view.

4.6. Seeding an instance
