I have 200 URLs that I need to redirect to new URLs
e.g.
http://abc.com/one/p-SF10 -----> http://abc.com/one/p-SF134
http://abc.com/one/p-SM28 -----> http://abc.com/one/p-SM28
http://abc.com/one/p-KH83 -----> http://abc.com/one/p-KH194

On Apache it was very simple to do in .htaccess like:

Redirect 301 /one/p-SF10 http://www.abc.com/one/p-SF134
Redirect 301 /one/p-SM28 http://www.abc.com/one/p-SM28
Redirect 301 /onep-KH83 http://www.abc.com/one/p-KH194

I found one of the guides with following lines:

if ( $request_filename ~ oldpage/ ) {
rewrite ^ http://www.domain.com/newpage/? permanent;
}

My question here is do I need to create these 200 'if conditions'? Wouldn't it create a huge conditional loop and overload my server?

Server configuration:
I installed Nginx+php-fpm using VestCP and set the nginx template to wordpress from within VestCP which configured my nginx.conf automatically.
