CEON URI module on my Zencart not redirect old URL

I have CEON URI module on my Zencart site, and this is working good! The problem is that iff I change url on my site with this module I get new url but the old url give 404 error and does not work. Only the new url is working and old url not anymore. I need someone that can fix this and know how to fix! What I also want to is that this will be redirect good so my old url's on GOOGLE will be stay ranked and not go away. So redirect with Google rules. We need this for all our sites and we have 3 site but first we want to start with 1 site and iff its working we can do other sites as well. We have zencart version 1.3.9 Only reply please iff you have done this before the installing of this module and also for the version we have. Thanks!!!
