Overview
When upgrading to a new release, you might need to retrofit some of your modifications to the new release. Because it is a laborious process to recreate custom modifications each time you upgrade the software, the upgrade process preserves most of your custom modifications. This chapter explains how to integrate any custom modifications that the upgrade process did not preserve into your new Release 9.2 software. This integration, called retrofitting, enables refitting of your customizations that could not be merged into the new version of the software.
Retrofitting modifications only needs a Development Client with the upgraded software and the development tools provided with Release 9.2. These tools compare the customizations that Release 9.2 merged into the new software with any pathcode in the system. Thus, you can easily compare your upgraded modifications with a version of your modifications before the upgrade or with the pristine environment of the new release.
