That's a very good question, and I should have mentioned it in my earlier reply. I'm glad you asked 😃
Seeing as you're going from v5.2.1 to the latest, there's a couple of things to keep in mind. There will be a small amount of refactoring required (but nothing scary!). We have notes in our developer docs here to guide you. The key things to note are:
- The iOS SDK now has a minimum iOS version of 10.
- You may need to use a more up to date push notification handler if you aren't already.
- You may need to use a more up to date URL handler as well.
Other than that, it should be a quick upgrade! You'll also get access to a tonne of new features that weren't available in v5. Mobile Carousels are a particular favourite of mine 😉
