Alltel TP to Verizon TP2

If this has been asked already I apologized. I've been searching the internet and talking to Verizon reps both in the store and on the phone and cannot get a consistent answer. Here is my dilemma:
I have an Alltel Touch Pro and would like to upgrade to a Verizon Touch Pro 2. I currently have the Alltel Smart Choice 500 (aka Smart Pack) which includes 500 minutes, 10 My Circle, nights at 7, and unlimited text, pic/video messages, data and e-mail for $89.99. Verizon keeps telling me I will have to add a $29.99 data plan and I will lose my 10 My Circle numbers and 50 minutes of talk time and it will cost me $10.00 more. I find this hard to believe.
My question is has anybody had my similar situation and did you or didn't you have to switch plans? Can I upgrade and keep my plan the EXACT same as it is now? Any input would be greatly appreciated.
