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.
We try to be agile in developing and merging our features into branches when they are ready for use.
Today my presentation is confirmed: "Therefore, whoever binds forever: automate your tests". Maybe the German title will be the better understood: "PL/SQL: Drum test-automatisiere, wer sich sich ewig bindet!"
