Enterprises are looking at Grid computing as a technology of enormous potential. However, there are several issues which require immediate attention before Grid can become an important component of the IT infrastructure. One such issue is migration of legacy applications to the Grid environment. In such cases, it becomes imperative to understand whether the application performance would significantly improve on migration. In this paper an attempt is made to provide a systematic framework called the Grid Application Migration Framework (GAMF) for handling the migration process. The framework consists of Grid Code Analyzer (GCA), an independently deployable component which generates a Directed Acyclic Graph (DAG). The paper also proposes a DAG reducer algorithm for reducing the DAG. The framework is tested with several proprietary and open source C as well as Java codes. In the paper, we take three sample open source applications and demonstrate the usefulness of the framework. Finally, a small sample is analyzed and recoded to show that validity of the proposed mechanisms.
