I agree to testing all the customization on R12, the problem is we don't have that environment. For now, we as asking oracle give us the costing upgrade from 11.5.8 to R12 and the feedback is the average effort on each form is 1.5 manday and each report is 1 manday.
I just wondering if the data structure are not changing too much, the effort will be less than that and the customization will be done by ourseleves.As Gareth has noted, you can expect the data structures to vary considerably in some of the Core Financials modules. In our experience, the introduction of Sub-Ledger Accounting and the new E-Business Tax module presented some challenges.
In terms of Oracle's estimates, it's hard to say. I'm a DBA, not a developer, so it doesn't seem fair for me to judge development estimates. :-) The main point to consider is that Oracle understands what has changed in the data structures, but presumably your organization has a better understanding of your customizations. Even if it takes longer to migrate the customizations yourselves as you learn the revised data model, there may be long-term benefit to your organization to have that knowledge in-house.
Is it possible to have R12 environment for testing? Anyone counter that upgrade from 11.5.8 to R12?If you want to get a test system up and running quickly, so functional teams and end users can get an idea of what the system will look like, you can install a Vision instance. In my opinion, there's no substitute for testing a system using your own data instead of the canned Vision data. I understand, however, that the resources aren't always available to run a test upgrade during the early phases of planning a project like this one. If you can install a Vision instance at your site, you might be able to make more informed decisions about your customization effort. As an alternative, Solution Beacon offers access (free of charge) to a [hosted R12 Vision instance|http://www.solutionbeacon.com/tool_vision.htm]. I have not used their service, but I suspect that it does not permit access directly to the database.
Good luck!
