According to your config, [new] request to cl.domain.com/xx-xxx-689
will end up in "location ~* [a-zA-Z]+(\-)+689$", which has no proxy_pass
rules.  You should either duplicate proxy_pass rules within this location, or 
(better, faster, more scalable) separate pe.* and cl.* servers:

server {
    listen       80;
    server_name  pe.domain.com;

    location ~* [a-zA-Z]+(\-)+689$ {
        rewrite  ^  http://cl.domain.com$request_uri?;
    }

    ...
}

server {
    listen       80;
    server_name  www.domain.com domain.com cl.domain.com;

    ...
}

For identical config chunks within this servers you may want to 
use include.
