Would you please tell me how to correct the following sentence?

From A to B, from C to D does not imply any change in this field.

Thanks.

I simply can't get what the sentence means.
Does it mean nothing is changed in this field?

If so, I would say:
- it does not have any change from A to Z in this field.
