Noloco and OTAP

Hi,
A customer has developped a Noloco solution and asked me to help him with further developments. I would like to do this, but i like to develop changes in a save (O/T) environment (copy?). After acceptance (A) of the new functionality i would like to promote the change to the current solutions (P).
Can i/we use this Way of Working in a Noloco environment?
