Abstract. Most times the provision of e-govemment services is dealt with independency of the legacy system itself. As more complex transactional services are provided to the public and the degree of on-line interaction between e-government service users (Internet) and legacy system users (Intranet) increases, the integration between e-service provision platform and existing legacy information system becomes a one-way direction. Although current technological trends as the J2EE architecture and web service platform promise the seamless integration of any type of system, this is not always true. In this paper we discuss the implications of such integration and the strategic decisions made regarding legacy system renovation.
