Google’s John Mueller was asked whether redirecting the URL to the new URL would still pass the Core Web Vitals metric.
The short answer is yes, if you redirect page A to new page B, the Core Web Vitals indicators and signals from page A will move from page A to new page B.

My website is a 100% Core Web Vital pass and all the urls are Core Web Vital valid. Now I want to restructure my site, restructuring I mean to say that I want to change the URL to the better SEO friendly URL. So my first query is now I have already changed the URL so will the Core Web Vital metrics, whatever exist for my pages will be passed to the redirected URL?
That should be the case, yeah.
My understanding is that they [Core Web Vital metrics] would be [redirected]. Like any other signal from search if we see a redirect then we would forward the signals that we have and apply them to the new URL and it doesn’t matter so much if the URL looks different, it’s more that you’re moving from one URL to another URL.
Why is this not the obvious answer? Well, the Core Web Vitals metric applies to CRuX data, which is Chrome data from specific URLs of actual users.
Therefore, you would think that even if you redirect to a new URL from another URL, you need Google to collect user data from Chrome.
But John said no, those signals, the CWV signals, will also enter the new URL until I guess Google collects new data for the new URL.
