Question Question About Custom Post Templates

[Philbeaux]

Trying to wrap my head around creating some custom post templates and I'm wondering about something.
The templates will be for an already existing site with lots of posts and categories already created.
If i create a custom post template for a particular category that already has posts, when I assign the new template to the existing category - will all posts in that category be converted over to new template or are the posts created to the new template just going forward? I assume that I can edit the already existing posts over to the new templates as needed?

When you create your posts template and assign the rules/conditions it will pull the content to the new design.
