Custom templates for Migration Hub Orchestrator

You can customize the templates provided by AWS Migration Hub Orchestrator for your use case and save them for reuse. You must first use a template provided by Migration Hub Orchestrator to create a migration workflow. Once the migration workflow is created, you can proceed with making customizations to the workflow.

To help ensure that the custom template works as expected, we recommend that you run the customized workflow after making your changes. Once the updated migration workflow completes successfully, you can save your changes as a new custom template.

Prerequisites

The following prerequisites must be met to create custom templates:

  • If the AWS managed template that you will customize requires the Migration Hub Orchestrator plugin, you must configure it before running the workflow. For more information, see Run the workflow.

  • To create a migration workflow, you must have the resources required by your desired AWS managed template available.

  • If you are going to create steps in the workflow of the Automated type, ensure that the scripts are accessible using one of the following methods:

    • If the scripts for your custom template will be sourced from an Amazon Simple Storage Service (Amazon S3) location, the script files must be uploaded to an Amazon S3 bucket with the prefix migrationhub-orchestrator-. For more information, see Organizing objects using prefixes in the Amazon Simple Storage Service User Guide.

    • If the scripts for your template will be uploaded to the AWS Management Console, you must be able to upload a copy of the script from the device that you are using.
