Abstract:
Legacy Systems have become a challenge for many enterprises, which have been migrating its legacy systems towards new computational environments because of interoperability issues with modern technologies, high maintenance costs, and hiring expert staff who possess high legacy technologies background. In order to find a strategy to solve legacy systems concerns, several approaches and experiences were created for the last years. This paper presents a strengths and weaknesses analysis of 18 migration approaches.
