PFC applications intended for Appeon Web migration must be upgraded to be compliant with PFC 9 or later. Some legacy PFC applications are based on the PFC 5.0 PBLs that have been migrated to the newer version, and you should upgrade those applications to use the new PFC 9 or later PBLs.
The PFC PFCOLD.PBL library contains obsolete objects that are not supported for Appeon Web migration. If the original PowerBuilder application is a PFC application that uses objects in the PFCOLD.PBL library, you should remove the objects when upgrading the application to PFC 9 or later.
