Ring Video Doorbell 2nd generation 2023 same as Ring Battery Video Doorbell 2 1999

Is the [Ring Video Doorbell 2nd generation](https://en-uk.ring.com/products/video-doorbell-gen-2) that you sell today the exact same thing has the Ring Battery Video Doorbell 2 I purchased in 1999? I already read that new holes would have to be drilled if I upgrade but I need to replace mine and want to know if I can swap them like for like with minimal hassle.
