Motors versus VFD issue

[SparkyJunior]

Hi guys. I am working on a project where our client has a 150HP motor and a 150HP VFD driving it. They want to replace the motor with a 200HP motor and also the corresponding drive. However, they want to do this one at a time. Either replace the drive first and then the motor or the motor and then the drive. I have been told that you should replace the VFD first and then set the electronic overloads in the 200HP VFD to trip a 150HP motor.

Is there any scenario where you can replace the motor first and rive it with a smaller VFD? Any input would be appreciated.

Thanks
