What do you think $1 is set to here?

(Usually, it is "the last thing matched". So usually, it is worth making
sure that you match something immediately before using it.)

"regex" can include things inside parentheses, which are then available
as ${number} in "replacement".

   location /old/ {
     rewrite ^/old/(.*) /new/$1 permanent;
   }

will probably do what you want; but read about the question mark, in
case it matters.

Usually, the same config works the same way. If you've found a case where
that isn't the case, it may be worth investigating. But it is potentially
the *whole* config that matters here, where you use $1 without showing
where it is set.
