Hi Kelly,
Now that the product has been out for a couple months, I took a look through some of our technotes and customer cases in our database. I couldn't find anything directly saying that something will go wrong, but I did find a couple of technotes that might help in case something does go wrong:

http://support.veritas.com/docs/284568

From looking at them, a couple have a minor amount of hitcounts(web traffic), and most don't have any hits at all, so hopefully this doesn't scare you away from the upgrade. I just wanted to make sure you had all the information you needed in case you did run into any issues.
Please let us know if this helps resolve your question, and if not, what issues are you running into now.
Thanks.
