Oracle Webcenter Schemas and Tablespaces in 11.1.1.3 vs 11.1.1.4

I am in the process of patching/upgrading a Webcenter PS2 install (11.1.1.3) with UCM 10g to a Webcenter PS3 install (11.1.1.4) using the Weblogic migration tools, Patch Set Assistant to migrate the schemas and the ECM migration tools.

One of the things I was curious about was the RCU schemas and tablespace differences in PS2 vs PS3 … what stays and what goes? how much of it is different?
