Plan a phisical to virtual OT environment

I have two environments, IT and OT, my IT environment is already virtualized, my request is to study the way that we can convert the OT environment to virtual (VMware) including:
- benefits and value of the project
- migration scope
- inventory and classification
- best practices
- risk analysis
- timeline

I need someone who has already done this kind of project and aware of the deep details of problems that could face us
