redirect old domain example.com/subpages to respective newdomain.com/subpages using Nginx

Question

Let's say I have a old domain "example.com" and a new one "newdomain.com"

the old and new domains have the same sub location pages for example example.com/test1/ = newdomain.com/test1/ example.com/test2/ = newdomain.com/test2/ and so on

I need an Nginx rule to do redirects all subpages from the old domain to the new domain respective subpages
