How to break a big module into separate services while they have shared data?

I have a very big module ( >100K line ) that I want to break into a few modules to interact with other modules with Rest API. I know I have to break it over some meaningful modules. but however, they have shared data and I do not know what to do with these shared data? Should I duplicate shared entities? Should I use "view"s for shared entities? Should I use just id instead of foreign keys and call Rest API for each usage of shared data? or anything else?

Thank you

This is very, very hard question to answer, almost impossible. And there are multiple answers. Breaking monolith into smaller services is a topic of many books, tutorials, YT videos. It is almost a science. Actually, it is one of the starting points when learning about microservices or refactoring legacy system. So instead of asking should I do this or should I do that, go and read about the topic online. There is a huge number of resources.
