- Retail Transaction Service (RTS) is now Commerce Data Exchange: Real-time Service (CDE-RTS)
- Store Connect (SC) is now Commerce Data Exchange: Synch Service (CDE-SS)
- CDE-RTS is now an IIS web service instead of a windows service like RTS was
- Install of R2's CDE-RTS and CDE-SS are very different than RTS and SS. It is more complicated than previous versions of AX for Retail.
- CDE-RTS should not be on an PROD AOS server (now that it is IIS, it should be on an IIS server)whereas RTS was located on an PROD AOS.
- In upgrading to AX 2012 for Retail R2, there is backward compatibility with AX 2009 and 2012 for Retail. These will still be RTS windows services on the AOS like before.
One of the biggest features in the new R2 release is Microsoft's push towards Multi-channel sales and the consolidation and management of the components into a centralized location (AX) for a single point of control. Additionally, working in conjunction with SharePoint 2013, there is an awesome customer facing storefront that can be deployed 'out of the box' (OOTB). I'm sure I'll cover this in more detail in a later post as well as the OOTB Facebook integration for authentication.
