Test case versioning options?

Hello, I'm researching Zephyr options to include test case versioning in our already existing Zephyr test cases in Jira. My team is using Zephyr Essential but I cannot find a plugin upgrade that allows for this versioning. Is test case versioning not available in Jira? What options does Zephyr offer for test case versioning? What are the migration impacts to those options and pricing? 

Any information about this topic would be of great value. We are a midsize team (around 60 people) if this information is helpful for options. 

Thanks in advance.
