versions across projects?

[Todd Flynn]

This question is in reference to Atlassian Documentation: Managing versions

is it possible to share versioning across multiple projects within Jira? 

eg. We may want to organize our work into three projects: database, service layer and front-end. With this structure, we would want to map issues from those three projects to a single release (version) track.

I figured the answer out myself. Adding the same Fix Version to different projects works (but apparently there's no way to copy them between projects).

You are completely correct – They are specific to a project.
