I'm not a web development expert by any means, but I've become somewhat of a go-to person for it in my office. We're still using jQuery, even though it feels outdated, and I know that changing it is a much bigger task than I'm ready to tackle just now. Recently, we've been experiencing bugs related to a new checkout widget from our payment processor. After digging a bit, I discovered that our site is still running jQuery version 1.7.2, which was released back in 2012.
I'm wondering if simply updating to the latest version of jQuery will fix these issues, or if that could lead to new problems. Part of me thinks that since we're already using jQuery, upgrading shouldn't break anything. But another part of me worries about deprecated functions and potential problems cropping up due to the version gap. How should I balance my hope and concern about making this update?

Yeah, definitely. Update your jQuery library and test locally to see if anything goes haywire.
There are several known vulnerabilities with jQuery 1.7.2. Upgrading to 3.7.1 could resolve your checkout widget issues, and chances are, nothing else will break. Just keep in mind that working with outdated libraries, especially when handling payments, is a big risk.
The best way to approach this is to just update the jQuery version and see what breaks. It's a bit of trial and error, but you can fix what doesn't work afterwards.
You should definitely check out jquery-migrate. It can help with compatibility when updating to newer versions.
Consider looking at the release notes for jQuery. They’ll outline any breaking changes, which will give you a better idea of what you're up against. It’s better to go in prepared than to jump in blindly! And hopefully, you have solid tests in place just in case.
