Abstract

Ability to integrate legacy assets and reusing their functionality in modern web-enabled information systems are important features of new-generation technologies. In the paper, organisational challenges are discussed, a multiphase integration procedure is proposed, which enables step-by-step integration of legacy applications and extension of their functionality with new generation technologies. A decision model for selecting the most appropriate technology infrastructure is presented and several technologies are evaluated. The paper, which also presents a integration case study of a major mobile phone operator company, contributes to the general understanding of legacy systems integration, gives a solid basis for making a decision about the underlying technology and presents an integration procedure that provably works in practice.
