Migration Toolkit for Runtimes 

The tools, reports, and knowledge that help developers modernize applications to run in the cloud and deploy containers at scale.

Use cases and migration paths

The migration toolkit for runtimes contains a rich set of skill sets (rules and code hints) and supports multiple migration paths and use cases. The toolkit is highly extensible and customizable so you can build on existing skill sets or create your own. 

 

Application modernization and migration use cases

The migration toolkit for runtimes simplifies the migration and modernization of Java applications by examining application artifacts, including project source directories and application archives. The tool then produces an HTML report highlighting areas needing changes.

We've summarized the most commonly used migration paths in the following table.

[1] Although the migration toolkit for runtimes does not currently provide rules for this migration path, Red Hat Consulting can assist with migration from any source platform.

Other use cases

The migration toolkit for runtimes lets you create your own set of rules and hints to adapt to your own particular needs. One example is new transformation paths. Many developers use the tool for non-migration use cases as part of their build process (via Maven plug-in or command-line interface) in order to validate code on a regular basis against organizational standards or to ensure application portability. 

Another common use case is the enforcement of certain libraries and frameworks (using a single logging framework instead of pick-your own). You can also use the migration toolkit for runtimes to avoid the usage of proprietary libraries.

The rules development guide provides instructions about how to customize existing rules and create new rules and rule sets.

Migration toolkit for applications

If you have a Red Hat OpenShift subscription, we recommend using the migration toolkit for applications. It offers additional capabilities that focus on application portfolio management and collaborating across teams for modernization projects.
