Abstract: The current business landscape is forced to upgrade their older software platforms into newer, maintainable, and cloud friendly. The biggest of such changes is the migration of Microsoft applications to the new flexible and cross-platform .NET Core/.NET 5+ platforms rather than the old traditional .NET Framework. This paper outlines the various methods of doing this migration particularly when it is done in large organizations where the systems are highly complex and integrated. A general theoretical framework named Scalable Enterprise Migration Framework (SEMF) is offered, and it consists of key stages, such as assessment and planning, application segmentation, staged migration, and post-migration optimization. The review synthesizes the literature in the academic community, the industry, and the enterprise case study to explore the tools, trends, and measurements of these changes. Among the most important issues discussed are: there are technical debt, the system coupling, distribution of resources, and skills gaps. Lastly, the paper identifies the limitations of the research and the need to conduct future research in the field of systematic and organization-wide migration plans development that are applicable to the enterprise context.
