In general, those are two different solutions offered by Amadeus. Libra on Demand / HRM suites includes more comprehensive tools such as Libra+, Libra Rewards or Delphi.FDC (which is now called Amadeus Sales & Catering - Advanced Module). If you want to know more please reach out to the vendor directly. In licensing standpoint, although the interface part numbers are different they can be replaced. We strongly recommend you to reach out to the relevant Oracle Account Manager to guide you through.
