Hello RAPwebCSS, and welcome to the forums.
You have at least a couple of choices:
1. Place a 301 permanent redirect for the old URLs that you no longer use, pointing them to the most appropriate current URL that is a substitute. This will preserve at least some of the power of any backlinks that those URLs accumulated.
2. Wait for Google to spider the website again, and merely let it see the 404 response for the old URL, as well as follow the links to your new URLs. Google should get it all pretty well sorted al;l on its own.

Spidering is different for differnt websites - some are several times a day, others are as seldom as once a week. The Google crawl team has developed complex rules for how often they spider a site, and how deep they spider at any one time.
