Development organizations maintain separate environments for development, quality assurance and production etc. These environments execute independently and have their own deployment and own methods of traffic controlling that are handled locally. In such a process artefact allowed to be created only at development environment, tested in QA environment and then would promote to the production environment for promotion. In a API managing product company when moving API management products from one environment to another, all the created APIs need to migrate across different environments to save the developer time and effort at various environments. In order to achieve accurate and efficient migration, artefacts should be portable and transferable to any new environment without any major post migration changes and additional effort. In this paper, we present a more powerful, efficient and generalized CLI tool that can be used by any REST based API managing applications to perform API migration in a more precise manner. We analyzed the current migration techniques use by trending API Management products and identified the major sieve point that needed to be addressed. Taking those faults n to consideration we identified the appropriate mechanism to migrate APIs across different environments.
