Many organizations rely on legacy applications for critical business pro- cesses, even though it incurs a huge cost due to obsolete hardware, software, compiler and the like. Replacing the business critical legacy requires extensive expertise to understand business requirements, esti- mate and test coupled with high cost. To ensure a strict cost budget of legacy migration projects, migration specialists need assistance to understand the facts of the legacy application component in a short span of time to estimate and deliver the target components. Avail- able program assistance tools do not address the needs to migrate the legacy applications. We have designed an effective framework to extract the run-time behaviour of the legacy application like function point, complexity, memory accesses and the like so as to estimate the scope and requirements of an application. The framework contains support to comprehend existing legacy applications, develop and test the target application with business-rules, non-functional requirements (NFR), test data, etc. Then we have proposed a tool assisted Agile way-of-working principles by augmenting our tool-set to migrate the legacy application quickly and effciently. The target components can also be validated co- existentially by exchanging live data with the existing legacy. Designed toolset is built on an open-source dynamic instrumentation framework and can be plugged to a wide variety of run-time environments.

Rapid development of information technology and communication (ICT) has increased the use of information systems in organizations since a decade ago. At the same time, many organizations are still using old information systems to support their business, known as legacy systems. Even though these systems cause technical problems, but they are still used to support service delivery to the customer. These systems are also essential to organizations as they have been operated for many years and possess high business value. The operation of legacy systems cannot be stopped quickly, as it will affect daily business tasks. However, organizations with legacy systems need to think about the ability of the systems to support their future direction. Modernization of legacy systems needs to be implemented to ensure the systems are aligned with global changes as well as improving the competitiveness of the organizations. This study, therefore, reviewed the phases and factors involved in legacy systems modernization to identify gaps and their insufficiencies. There are many studies on legacy systems, but only a few have focused on the overall process of legacy systems modernization. Most studies on legacy systems are technical in nature and refer to specific aspects and phases of modernization. This study aims to provide overall guidance to the organizations in performing legacy systems modernization.

The evolution of technology has increased the complexity of software systems. Legacy systems pose challenges due to their monolithic architecture. To stay competitive, businesses need to modernize these systems, particularly by migrating to cloud platforms. This transition is complex, requiring careful consideration of business needs, technical capabilities, and organizational culture. Financial institutions face issues like inflexibility, high maintenance costs, and limited analytical capabilities. This chapter explores modernization strategies such as upgrading components, integrating new technologies like Salesforce, or forming strategic partnerships. Salesforce, with its cloud-based architecture, offers improved data governance, regulatory compliance, cost savings, and better decision-making. The research highlights the importance of modernization to overcome legacy system limitations and emphasizes Salesforce's potential in driving organizational success in the digital era.
