Already 4 years we plan the upgrade from 11c to a new supported version. If you speak german and you are interested in some of our experiences, you should come and attend my presentation at DOAG 2020 Wednesday, Nov. 18, 15:00 online.
I have presented last week on DOAG 2014 in Nuremberg. For all non DOAG members - you can find the german presentation on Slideshare too.
The presentation is ready, time for travelling now.
Today the official program is online for DOAG conference 2014 in Nuremberg. My presentation is confirmed "The Dirty Dozen - ADF Migration to 12c in the IKB".
