We have just published a reference to an Oracle customer, Callista, talking about their Forms upgrade experiences and future development plans.

I'm actually seeing a huge number of Forms customers upgrading to 11g but it can take some time and effort for customers to formally agree to be a reference story, so I'm grateful to Callista for taking the time to become an 11g upgrade reference.  We have a number of other customers who are writing up their upgrade experiences and we hope to have these on OTN in the coming months.

You can access this from the Forms home page on OTN.
