Oracle ERP User Network Collaborate with Professionals working on Oracle ERP(Oracle Apps) including EBusiness Suite (R12, 11i), Fusion, Peoplesoft, JDE, Siebel, Hyperion, OBIEE, SOA etc.

Our Accounting users are not happy with the Install Base module and are contemplating an uninstall and determine another process to integrate Inventory to Fixed Assets.  Has anyone ever uninstalled an Oracle Module and if so, can you point me to any documentation on the best method for this?  I am trying to determine impacts and how to analyze.  I am sure we will have to provide additional development for a new process. 

My recommendation will be to upgrade to R12 and re-install the setups and process clean in a new upgraded environment.  For now, I need to document all the reasons that uninstalling an integrated module (Inventory, Install Base, FA and Payables) is a major effort and not as easy as just 'ripping it out'.

Any guidance, will be greatly appreciated!

Thanks,
Lisa
