We are moving to a new TREP and need to publish structured product prices. For this I was told that I need to migrate to OMM (using Java). Looking into this and I am a bit confused, I found OMM examples in both RFA and UPA. The code I am having to migrate was written using RFA, how can I know if it is already using OMM or not? For example, both the RFA OMM example and our code uses com.reuters.rfa.common.EventQueue. I would like to have to change a minimum of the code because it is a legacy applicartion.
