CA GENER/OL executes on VSE and z/OS operating systems as packaged. However, some steps to follow when converting from VSE to z/OS to be aware of:
1) There is no conversion utility required.
2) Use IDCAMS REPRO to move your libraries from the VSE system to the z/OS system, for example, SGTLIBC, SGTLIBP, SGTLIB1, or any other user libraries. These files are standard KDSD files.
3) Be sure to install CA GENER/OL from the z/OS install package available on supportonline. Update the installed product with all current PTFs to bring the product current.
Be advised that you may have IBM Cobol issues between the Cobol/LE environment and operating systems. These do not affect CA GENER/OL but you could see errors within CA GENER/OL. Utilize the CA GENER/OL diagnostic tools to assist you but in most cases some Cobol programs will require a re-compile.
