Alce: Predicting Software Migration

2011

I am heartily thankful to my supervisor, Dr. Shukor Abd Razak , whose encouragement, guidance and support from the initial to the final level enabled me to develop an understanding of the subject. It is a pleasure to thank those who made this thesis possible, specially to all my ex-colleagues for their endless supports and encouragments. Lastly, I offer my regards and blessings to all of those who supported me in any respect during the completion of the project.

Challenges in Service Oriented Architecture and Cloud Computing Environments

Established software systems usually represent important assets, which are worth preserving in new software structures, to combine already proven functionality with the benefits of new technologies. The SOAMIG project is aimed at developing an adaptable migration process model with an accompanying tool support based on model-driven technologies. This process model, which combines reverse and forward engineering techniques, was applied in two different case studies on migrating a monolithic software system to service-oriented architecture and to a transformation-based language migration from COBOL to Java.

, has conducted several free and open source software (FOSS) migration projects for various organizations. The experience gained from these projects enabled the creation of a FOSS Migration Methodology which documented how the technical elements of a project of this kind should be executed. Despite the usefulness of this methodology, the projects that have been undertaken experienced difficulties that were, in most cases, directly related to their management. This research aims to improve the methodology and minimize management-related challenges thereby improving the quality of migration projects. The proposed methodology was applied in a project that ran in a higher education organization and the results prove that the methodology enhanced the quality of the migration project.

Abstract One approach to dealing with spiraling maintenance costs, manpower shortages and frequent breakdowns for legacy code is to" migrate" the code into a new platform and/or programming language. The objective of this paper is to explore the feasibility of semi-automating such a migration process in the presence of performance and other constraints for the migrant code. In particular, the paper reports on an experiment involving a medium-size software system written in PL/IX.

INTRODUCTION Most commercially built information systems are based on traditional technologies preventing them from unfolding their full potential in future software development. Service-Oriented Archi-tectures (SOA) (Arsanjani, et al., 2008; Gold, Knight, Mohan, & Munro, 2004) provide a modern and promising approach to increase flexibility in software adaptation, maintenance and evolution by referring to the underlying business processes to be supported by the software systems. Necessary functionality is specified by services which

Computers are getting faster and faster; the operating systems are getting more sophisticated. Often, these improvements necessitate that we migrate the existing software to the new platform. In the ideal world, the migrated software should run perfectly well on a new platform; however, in reality, when we try that, thousands of errors appear, errors that need correcting. As a result, software migration is usually a very timeconsuming process. A natural way to speed up this process is to take into account that errors naturally fall into different categories, and often, a common correction can be applied to all error from a given category. To efficiently use this idea, it is desirable to estimate the number of errors of different type. In this paper, we show how imprecise expert knowledge about such errors can be used to produce very realistic estimates.

Software migration is an inherently knowledge intensive activity, which requires a great amount of expertise and experience from different sources. Knowledge-based approach to software migration has a great potential for improving traditional approaches. In this paper, an Ontology-based PlaTform-specIfic software Migration Approach (OPTIMA) is proposed. Firstly, the background and the related work are introduced, and the ontology design for platformspecific software migration is discussed. Secondly, the architecture and workflow of OPTIMA are illustrated with a prototype tool. Thirdly, the case study is used for experiments with the approach and the prototype tool, and finally, the conclusion is drawn and further research directions are speculated.

The purpose of the study is to demonstrate the feasibility of automated code migration to a new set of programming libraries. Code migration is a common task in modern software projects. For example, it may arise when a project should be ported to a new library or to a new platform. The developed method and tool are based on the previously created by the authors formalism for describing libraries semantics. The formalism specifies a library behavior using a system of extended finite state machines (EFSM). The mentioned EFSMs are a foundation of the code migration method. This paper outlines the metamodel designed to specify library descriptions and proposes easy to use domain-specific language (DSL), which can be used to define models for particular libraries. The mentioned metamodel directly forms the code migration method which is also described in the paper. A process of migration splits into five steps, and for each step the algorithm was developed. Models and algorithms were implemented in the prototype of an automated code migration tool. The prototype was tested on both artificial code examples and several realworld open source projects. Results of the experiment indicate that code migration can be successfully automated with developed tool acting as the proof of concept. Models and methods designed form a basis for more powerful migration methods and full-featured automated code migration tools.

In this paper, we report on the development of a methodology for the evolution of software towards new architectures. In our approach, we represent source code as graphs. This enables the use of graph transformation rules, allowing the automation of the transformation process. Prior to its model representation, the source code is subject to a preparatory step of semi-automatic code annotation according to the contribution of each of its parts in the target architecture. This paper first describes the overall methodology and then focuses on the code annotation and model transformation parts. We also discuss issues of the implementation of the approach based on existing tools.

The Modernization of Legacy System is made appealing by several features of SOA in today’s world and migration of applications to the Cloud. In order to carry out a comparative review on the decades old migration approaches are classified in to Early Migration Approaches, SOA Migration Approaches and Cloud Migration. A comparative review is presented among this categories to depict the migration requirements. This paper also provides the research opportunities in the context of migration of legacy systems focusing on Legacy System Understanding, Study of Artefacts and their Relationships.
