The description upon entering these forums says this is not a support forum so I hope this is the proper place to post this question and get a response!
I just downloaded today the new Unity Hub and Editor Unity 2019.3.0ab and uninstalled all my older versions of Unity to preserve disk space. For older projects that I created with 2018 and earlier, what do I have to do to upgrade them to the 2019 version. In the past, all you had to do was open up the editor, and the system would prompt you to upgrade or revert to the past. In this version, it asks you to load up the past version with no chance to load up the new 2019 version.
