Migrating Web frameworks using water transformations

We propose an approach (based on water transformations) to migrate Web applications between various Web development frameworks. This migration process preserves the structure of the code and the location of comments to ease future manual maintenance of the migrated code. Developers can move their applications to the framework that meets their current needs instead of being locked into their initial development framework. We give an example of using our approach to migrate a Web application written using active server pages (ASP) framework to Netscape server pages (NSP) framework.
