We are making significant URL changes to our website. Because the URL is changing the social sharing buttons are not showing previous shared counts. I have read several resources like the one below that is linked to in several other similar questions.

However I would love to get some insight from someone who has done this and there thoughts on the outcome. As an ecommerce site the "Social Proof" of products that have received social shares is a big deal to us.
In Mike Kings example above the counts are being attributed to the OLD URL which is problematic over time. Our site has been up for over 12 years and has had several major changes to it, and I am certain there will be more in the future, being able to preserve the count on the current URL is ideal. While I agree with him that over time I believe social platforms will let data pass through 301 redirects, until then I need to find the best way to do this. Also with his example and others I have seen people mention than new likes from the new url can reset the counter. If you have gone through this and have ideas pleas share them. I look forward to your thoughts thanks.
