SMP3 - Admin / Architect:

Hi, I have a question on SMP3 and Administration/Architecture...:In the current state of SMP3 and SAP Gateway 2. How does the depreciation of the included SMP3 gateway affect current installations. For instance, do I now have to install SMP3 with OData connections to the Netweaver 7.4 Gateway 2.0 or does the current SMP3 still contain the integrated gateway? If so please point to the documentation that explains the connection between the external Gateway 2.0.
