If you already used AIM's methodology in your projects you will not find a very big difference, majority of task and deliverable remain same, but they reclassified under different Process. Lets take a quick look, if you take first on Phases then AIM was based out of 6 phases where as OUM only 5.
When you compare the process ,12 Processes was mentioned in AIM , where as 14 process is documented in OUM (Implement Focus) as per list and figure below.
OUM is prepared in such a way to speak universal language in all their approach towards Phases, Process and Templates. Now you can have one methodology to implement any kind of software product, those can be within the umbrella of oracle or even out of that. Following OUM will be more than sufficient to plan and process with a project.
