Application Migration in HE

There are different application migration requirements depending on the CA Gen release that the application is migrating from and the type of linkage the application uses to invoke the various components of that application.

To aid migration from releases of Gen before release 7, use the Compatibility setting for the Dynamically Link Packaging property. Its purpose is to:

• Enable CA Gen 8.5 applications (which are built as DLLs) to call components that are built as non-DLL load modules.
• Optionally, build components that cannot be DLLs as non-DLLs that use the same z/OS runtime as CA Gen 8.5 DLL applications.

Note: Since the Compatibility feature was not available in AllFusion Gen 7 or AllFusion Gen 7.5, components that are previously migrated to these releases became DLLs. Migration information from these releases to CA Gen 8.5 does not mention Compatibility.

Note: For more information about migrating to CA Gen 8.5, see the Release Notes.
