We are upgrading from EnterPriseOne 8.9 to 9.0.1. Custom objects need to be retrofitted. So what should be the percentage effort required compared to original development effort. For ex:. If an object is created in 100 Manhours during original development in 8.9, what should be the manhours for retrofitting using Boomerang. I am sure it will not be possible to say exact, but let me know a rough estimated figure.
