Replacing old urls in database

I installed Local, set up a staging site, and used Updraft to restore files from my current blog. It wanted me to pay for Migrator to change all the urls in the database but I couldn’t get permission to pay for it for this one thing and so I restored without doing that. Now that I have, how can I do a find and replace on the local database to change the urls so the staging site doesn’t link all posts to my existing site?
