The present application is directed towards systems and methods for automatic retrofitting of customized code objects during transformation of a system from a source installation to a target installation. In many instances, new objects may be created or objects modified on an online or production system while a development system is being upgraded. Simply copying the upgraded development system to the production system when complete would delete these new objects or modifications. Accordingly, the modifications or new objects may need to be retrofitted, or propagated to the development system and upgraded or transformed for compatibility with the new software, prior to placing the system online.
