Interested in upgrading to the New Standard version of CRM

Interested in upgrading to the New Standard version of CRM

Hello,

I have the old "pro" version of CRM for $12/mth... if I upgrade to the new "Standard" version of CRM for $12/mth, will I still have all the same features, but more?  Should I do this or not?  I don't want to upgrade and then discover that I have less features then what I had on the old system.

Please advise?
