This sounds like quite a jump in versions you are making, do you have any of the versions inbetween? I would recommend reading the release notes and what's new sections of the help for each of these versions. I don't know that anything was removed, but I am not familiar with the version you are coming from. There were a lot of UI changes for version 8, so it is probably worth while to review the Getting Started document also to familiarize yourself with the new environment.
I hope this helps, good luck with your upgrade.
