I've been customizing a style on a test server. It's pretty much done, and I'm ready to import to our live site. My question is, if the live site has 10 plugins with templates (that the test site doesn't have), what will happen to those templates when I import the new style? I just want the live site to keep those plugin templates as they are. Do I need to first install all the plugins on my test site too, and then export?
