Hi All,
I would like to build ITK5.0.1 using VS2017 on Windows 10 and use it for my project which was developed on ITK4.2 before.
I think I need to enable ITK4 in the CMake setting, right?
Also, I used VTK5.8 in my project before and want to replace it with VTK8.2. How to build VTK8.2 so I do not need to change much code.
Thanks a lot.
YL

ITKv5 migration guide can be found [here](https://github.com/InsightSoftwareConsortium/ITK/blob/master/Documentation/ITK5MigrationGuide.md).
VTK migration can be aided by the [version-to-version changes](https://vtk.org/Wiki/VTK/Roadmap), as well as asking on the [VTK forum](https://discourse.vtk.org).
