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.)

http://nginx.org/r/rewrite

"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.
