Hello everyone, I'm new to the DNN community. I've inherited a DNN (5.05.01) website at work. I'm looking to upgrade it to DNN 6 or DNN 7. I still haven't decided what is the best option. I would appreciate it if someone can explain to me the major differences/changes between DNN 5, 6 and 7. What should I consider before upgrading to 6 or 7? Which version is best 6 or 7?

I know I'm asking a lot of BIG questions, but I'm new to DNN and I'm kind of lost. I appreciate any help that anyone can provide.

Thanks much!
