Application Migration

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

To aid migration from releases of AllFusion Gen before release 7, the Compatibility setting for the Dynamically Link Packaging property can be used.

Its purpose is to:

• Enable CA Gen 8.5 applications (which are built as DLLs) to call components built as non-DLL load modules.
• Optionally, build components that cannot be DLLs as non-DLLs and have them 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 7.5, any component previously migrated to these releases became DLLs. Thus migration information from these releases to CA Gen 8.5 does not mention Compatibility.

For more information about Compatibility and migrating to CA Gen 8.5, see the Release Notes of this release as well as the previous releases.
