A Migration Management Framework Proposal For Cobol/cics Based Mainframes

Today, mainframes contain a considerable portion of business applications worldwide. It is estimated that the current inventory of production COBOL running on mainframes is 150 to 200 billion lines of code. Despite the efforts to change within the mainframe environment, these mainframes, nowadays, face major problems for host organizations due to a combined set of financial, business related, technical and organizational problems. Moreover, the factors like diminishing resources (COBOL programmers), lack of documentation, inability to integrate with other systems, increasing maintenance costs, etc. have caused the organizations search for migration solutions. To overcome this problem within the context of modernization, over the years several main migration approaches that ranges from simple screen scraping methods to complete re-write of applications or re-hosting of platforms have been developed.
To contribute to the solution of this overall problem, this thesis proposes a methodology framework specifically for the COBOL/CICS based mainframes. The research studies in this topic within this field are mainly focused on the technical aspects whereas our concentration is covering not only that but the other essential aspects of the problem domain. These are organizational view, project management view and process view. Within the thesis study, a special interest is given to the modernization strategy selection among migration, rewrite, packaged and do-nothing alternatives. Experimental results are also provided within the thesis to prove the usability of the approach for this selection.
