A predetermined change to a software system having a large number of highly connected and interrelated executables and data files is accomplished using a redevelopment database which is generated from a software library. The redevelopment database maintain resource and relational information on the executables and data files. This information is used by a partitioner which creates groups of executables and data files which have minimal connections to executables and data files outside a given group. The groups are assigned to a resource, with the resource performing the software changes in a given group with the aid of software change mechanisms. After the changes in a group are completed, a configuration management system of the software system receives the newly modified software, updating the software system. The configuration management system also notifies the redevelopment database so that the relational and resource information of the redevelopment database remains up to date, and continues to support the day-to-day modifications other than the predetermined software change.
