Modernization of Legacy Systems
Proceedings of the Sixth International Conference on Computer and Communication Technology 2015, 2015A number of key organizations are sustaining the decades old complex legacy systems despite their types of services and operating environment. Cloud computing provides numerous processes, tools and methods to emphasize upon the pay-as-per-use utility models.

Legacy systems: coping with success
IEEE Software, 1995Legacy systems may be defined informally as "large software systems that we don't know how to cope with but that are vital to our organization". Legacy software was written years ago using outdated techniques, yet it continues to do useful work. Migrating and updating this baggage from our past has technical and nontechnical challenges, ranging from ...

Iterative reengineering of legacy systems
IEEE Transactions on Software Engineering, 2003During its life, a legacy system is subjected to many maintenance activities, which cause degradation of the quality of the system: When this degradation exceeds a critical threshold, the legacy system needs to be reengineered. In order to preserve the asset represented by the legacy system, the familiarity with it gained by the system's maintainers ...

Improving Legacy Systems Maintainability
Information Systems Management, 1997The key to the dilemma posed by vital systems that consume large amounts of staff resources lies in improving systems maintainability. This article classifies legacy systems into four broad categories and presents improvement techniques tailored to each. Fallacies that contribute to critical investment errors are also discussed.

Decision model for legacy systems
IEE Proceedings - Software, 1999Legacy systems pose major problems for industry-existing software seems so difficult and expensive to change quickly to keep up with the needs of business. The authors firstly summarise the general problems with modifying existing software-termed software maintenance-and then address the problems of legacy systems.

Model Generation for Legacy Systems
2004We propose the use of (semi-) automatically extrapolated models as a means for coping with legacy systems: a focused way of testing systems for their behavioral properties allows the construction of expressive behavioral hypothesis models, and therefore extends the range of formal methods to ‘black box’ scenarios, which are dominant in industrial ...

Reengineering legacy embedded systems
IEEE Design & Test of Computers, 1999Systems that require reengineering are a fact of life in both the commercial and military arenas. The authors have developed a systematic methodology based on virtual prototyping, with accompanying tools and libraries, for rapidly upgrading electronic systems.

Legacy System Cataloging Facility
Proceedings of 2nd Working Conference on Reverse Engineering, 2002Describes a software model construction and management tool that provides a foundation for legacy systems modeling, analysis and transformation on an enterprise scale. The Legacy System Cataloging Facility provides a scalable, multi-tiered hierarchical storage mechanism for managing legacy system as persistent, high-fidelity software models within a ...

Cloud computing is a paradigm which has changed the way organizations develop, manage, and deploy their applications. Most of the resources are available at low costs in this technology and it creates new opportunities for organizations to move their existing applications to the cloud for modernization. But this modernization also comes at a price. The

A decisional framework for legacy system management
Proceedings IEEE International Conference on Software Maintenance. ICSM 2001, 2002Making a decision about how to evolve a legacy system cannot be made spontaneously; rather, it requires a decisional framework that takes into account several factors including software value, risk analysis, and cost estimation. We present a decisional framework to manage legacy systems that exploits an assessment model and a taxonomy of maintenance ...
