Nginx rewrite send all query params except one

I need to remove a certain query param from the request URI, before redirecting the user from domain1.com to domain2.com. The query param is migrate.

So from this URL: domain1.com/check?migrate=true&uuid=1821

I want to take the user to this URL: domain2.com/check?uuid=1821

There can be a lot more query params, and I want to keep them all except migrate

You will need to apply a regular expression to a variable that contains the entire query string - so either $request_uri or $args are possible candidates.

To redirect just /check, you could use:

location = /check {
    if ($args ~* ^(.*&)?migrate=[^&]*(&(.*))?$)
        return 301 http://domain2.com$uri?$1$3;
    }
    return 301 http://domain2.com$uri?$args;
}

See this caution on the use of if.
