I jotted down few points, you may go ahead with these suitable differences :

1)  11i contains oracle forms basis application but R12 is now Oracle forms with HTML pages.

2)  Database Version in 11i (11.5.9 & 11.5.10) was 9i Rel 2 where as in Release 12 its 10g R2 (10.2.0.2)

3)  HTTP Server or Web Server in R12 is Version 10.1.3 which is built on Apache version 1.3.34. In apps 11i it is Version 1.0.2.2.2 built on Apache Version     1.3.19

4)  Jserv in apps 11i is replaced by OC4J (mod_jserv is replaced by mod_oc4j) in R12

5)  Forms Version 6i in Apps 11i is replaced by Forms 10.1.2.0.2 in R12

6)  Reports Version 6i in Apps 11i is replaced by Reports 10.1.2.0.2 in R12

7)  JDBC version is changed from version 9 in apps 11i to version 10.2.0 in Apps R12

8)  modplsql or mod_pls is removed from Apps R12

9)  Java processes use JDK/JRE version 1.5.0 in R12 against JDK version 1.3.1 or 1.4.2 in Apps 11i

x) New INSTANCE_TOP added within Application tier servers in Release 12 for configuration and log files.
