New RN

It has been my experience that starting pay is negotiable. I have accepted the offered pay a few times over the years only to find out RN's doing the same job as me were being paid more, sometimes a lot more for various reasons. These days I wait for their offer and immediately ask for more based on (and here you will need to tailor it) years of experience, previous pay levels, cost of living etc. 

I think it will depend on the organization and the role LPNs served.  While both are a nurse, it is a different level of nursing and depending on the job description, different skill levels. While you are not a new nurse, you would still be considered a new RN, so depending on that you could likely make the same salary or hourly wage as a new RN
