Purpose of this information:

This information provides an overview of the steps z/OS customers must take to migrate applications for use with z/OS® Language Environment®. The information will not provide a comprehensive guide to the migration process; rather, it is designed to help users create a broad migration strategy. The information will help users identify which modules can be migrated first, and which will require relinking or recompiling. It also explains how to use Language Environment runtime options to achieve behavior that is compatible with the old modules.

Who should read this information:

This information is intended for application developers. These customers may not necessarily be migrating to a new language compiler. Familiarity with the runtime libraries of the different languages, and an understanding of the basics of linking and running applications, are assumed.
