Is there any script that can transform animated standard max camera into vray camera with the same animation path?
Use the align tool then add a link, works well enough. Just need to keep your standard cameras in the scene and only use those for path editing.
Align and link works well, you could also copy the transform keys from the regular camera and paste them on the vraycam in trackview.
i intentionally left out animation for the script converter precisely because of the many ways a camera might be animated. brains and a human hand normally get better results

just instance the transform controller to the new camera
thank you guys. I instanced transformation frames form max cam to vray one.
