The instructions on how to upgrade to ZVJ are
here. Any and all information you might need are just above your post in the stickies. Get used to reading all of them, front to back, and trying to understand what they're telling you to do. If you need help with a step of the process, ask in the appropriate original thread.
You're not the first person to ask in their own thread how to do something in a sticky, but don't make it a habit. If you can, find a thread with a similar question and post there. Especially in the Dev section, try to limit new threads to posting new content and that sort of thing. It's why we have the sticky topics at the top.
All that said, welcome! And I hope you get that thing upgraded!
