Abstract

Legacy systems continue to play an important role in the implementation of information systems in organisations. Many large organisations still rely heavily on these systems in delivering critical services. Legacy systems are important assets of organisations as they contain important business logics and data over several years. Although these systems are critical to the business yet organisations have to face technical difficulties and unnecessary expenses in maintaining the systems. In order to continue providing quality services in line with the global changes, legacy systems need to be refreshed through modernisation. This study therefore reviewed the phases involved in legacy systems modernisation to identify gaps and their insufficiencies. It aims to provide an overall guidance to the organisations in performing legacy systems modernisation.

遗留系统现代化的实施阶段
遗留系统继续在组织信息系统的实施中发挥重要作用。许多大型组织在提供关键服务时仍然严重依赖这些系统。遗留系统是组织的重要资产,因为它们包含多年来重要的业务逻辑和数据。虽然这些系统对业务至关重要,但组织必须面对维护系统的技术困难和不必要的费用。为了继续提供符合全球变化的优质服务,需要通过现代化更新遗留系统。因此,本研究回顾了遗留系统现代化所涉及的阶段,以确定差距和不足之处。它旨在为执行遗留系统现代化的组织提供总体指导。
