The following SAS DOC should be of use, as it relates to SAS Base and migrating between OS platforms. If you choose a Unix System Services (USS) to maintain your SAS data warehouse in z/OS, rather than using SAS data libraries and catalogs maintained as z/OS MVS datasets, you will see similarities in data structures and hierarchy.
Also, if your application is generating web-content, you will want to consider how and where to publish your SAS-generated web HTML, images and other related code, possibly choosing the HTTP web server, provided with the z/OS base operating system (no additional cost).
It will be important to inventory your SAS DI application components, databases, source code, data mapping tables, external DBMS references, and other matter, in order to decide how best to plan, test and move to the production environment. And, consider the need to develop, validate and maintain a test vs. production (ongoing admin) strategy for your continuous application development operation.
