If you’ve built a course under 1.9.8 it should work fine–but go test it before you actually need to use the site. I’ve tested most of the core functionality and found no problems. But it was a cheap and cheerful test.
Unfortunately I cannot provide tech support if you do have challenges…there’s a surfeit of resources online to help though, including videos, wikis and webpages. But if you have any feedback, comment below!
