Hi papergecko,
Thanks for getting in touch. The best way to update from an old version is to do it in gradual steps. I’d recommend updating all of the plugins to 3.5, and then to 3.12, and then finally to 4.0 (or 4.0.1 or .2, as needed).
The first thing you’ll need to do is purchase a license for Events Calendar PRO and Eventbrite Tickets. That way you’ll have access to the latest version. We can then provide the older versions for you via email or here in the forum- just ask!
A lot of changes have happened since 3.0, so you’ll want to review our release notes for versionsĀ 3.1-4.0. You’ll particularly want to pay attention to the Things to Be Aware Of posts that we do for each major release. There are also some major changes in how to configure the Eventbrite Tickets plugin, so you will definitely want to review our tutorial.
Because so many things have changed since 3.0, it is likely that you’ll need to make at least some changes to your theme to get everything looking as you want. We always recommend that people update on a test site first so that they can watch out for these kinds of issues. While we can’t provide in-depth support for theming, we always do our best to help out. Once you have your licenses, you’ll be able to post in the premium forumsĀ for tips from our support team.
Cheers,
Leah
