No you will not need to claim UC unless there are other reasons that you need to, such as a new claim for Housing Benefit.
At some time in the future, probably not in the next two years, there will be a managed transfer of ESA claimants to UC and what is called New ESA, at the moment there are no details of how this will be done.
