Wordpress Change domain of WordPress and do 301 wildcard redirect

do not delete the old domain nginx vhost config files, just edit their server{} context and do a 302 temp redirect to the new domain and let that run for a few weeks to be sure before changing to 301 permanent redirect

key to testing is using 302 temp redirect first in a private incognito browser session otherwise the problems you can experience may end up being due to browser caching or 301 permanent redirects unless you clear browser cache and reboot local computer(s) and even then some web browsers don't let go of 301 permanent redirect browser cache that willingly

You can test in SSH via curl to check headers for location field (where the redirect goes) using the following commands:

Code (Text):

curl -I http://domain.com

Code (Text):

curl -I http://www.domain.com

 

correct

for domain redirects using return directive is best within it's server{} context so to redirect old-name.com and it's equivalent www version to the new-name.com www version would be

Code (Text):

server {
   server_name old-name.com www.old-name.com;
   return 302 $scheme://www.new-name.com$request_uri;
}

this technically can be placed in your old domain nginx vhost, or if you remove it, in your new domain nginx vhost as separate server{} context

so your vhost below would redirect old-name.com and it's equivalent www version + non-www new-name.com domain to the new-name.com www version via 3 separate server{} contexts in the new domain nginx vhost file

Code (Text):

server {
   server_name old-name.com www.old-name.com;
   return 302 $scheme://www.new-name.com$request_uri;
}

server {
   server_name new-name.com;
   return 302 $scheme://www.new-name.com$request_uri;
}

server {
   server_name www.new-name.com;
   ... your vhost config settings ....
}
