Passive income: NO

Starting an Intelligent Code Migration and Modernization Service can potentially lead to passive income, but it is not guaranteed for most individuals. To make this side hustle passive, one would need to set up efficient automation tools, establish clear processes, and potentially outsource certain tasks. While some people have been able to achieve passive income in this field, it tends to be more common for a few outliers rather than the majority. It requires a significant initial time investment to streamline operations and build a client base. However, with dedication and strategic planning, passive income is achievable in the long run for some practitioners. It is essential to be realistic about the time and effort required before expecting significant passive income streams.
