I need a few plugins, and their databases moved from and old site, to the new live site

I need a few plugins, and their databases moved from and old site (which is now on the dev site), to the new live site. both are still in the same server. we just need it done because the client doesn't want to deal with all the login information. I started using the duplicator plugin, so I have all the file folders, but I don't know which database tables I need to copy.
