I agree with the above comments; I have the same experience. I purchased Thesis , and worked hard to build my website. Then I bought the upgrade to before it even came out, because they sent an email offering discounts for early adopters. I actually never upgraded my website, because I would more or less have to recreate my site. Too much work. There is no migration tool from to . They just abandoned their customers. Their technical support is also not very helpful: they seem to be ignorant of the fact that I am an end-user, not a developer. It is as if I am just not good enough for them.
