Abstract
Today, most of the organizations trust on their age old legacy applications, to support their business-critical systems. However, there are several critical concerns, as maintainability and scalability issues, associated with the legacy system. In this background, cloud services offer a more agile and cost effective platform, to support business applications and IT infrastructure. As the adoption of cloud services has been increasing recently and so has been the academic research in cloud migration. However, there is a genuine need of secondary study to further strengthen this research. The primary objective of this paper is to scientifically and systematically identify, categorize and compare the existing research work in the area of legacy to cloud migration. The paper has also endeavored to consolidate the research on Security issues, which is prime factor hindering the adoption of cloud through classifying the studies on secure cloud migration. SLR (Systematic Literature Review) of thirty selected papers, published from 2009 to 2014 was conducted to properly understand the nuances of the security framework. To categorize the selected studies, authors have proposed a conceptual model for cloud migration which has resulted in a resource base of existing solutions for cloud migration. This study concludes that cloud migration research is in seminal stage but simultaneously it is also evolving and maturing, with increasing participation from academics and industry alike. The paper also identifies the need for a secure migration model, which can fortify organization’s trust into cloud migration and facilitate necessary tool support to automate the migration process.

RQ3- When did research on cloud migration become active in computing community and how it is reported? RQ4- What are the obstacles in the cloud migration process and how it is being researched?
Summary
Cloud computing has created a strong buzz around, both in academia and in the industry. Many SMEs (Small and Medium Enterprises) and IT companies view this technology as an opportunity for considerable business growth thereby creating competitive advantage (Buyya et al 2009; Andrikopoulos et al 2013). Larger enterprises are attempting to leverage this technology by considering the business continuity strategies for their exponential growth Given the inherent advantages of cloud computing and the desire to migrate to cloud, there has been noteworthy research in the area of cloud migration (Khadka et al 2013; Andrikopoulos et al 2013). Most of the approaches have proposed frameworks, techniques, processes and methods which help in the migration and assist in decision process for migrating to cloud. For most of these approaches, the software
