V9 Xpress installation from Alibre v9 setup download:
I have installed the v9 setup from the Alibre website to upgrade my grandsons v8.2 Xpress installation to v9. While there is not yet the ability to register v9, nor a server, it does retain all the registered features of 8.2 and the post 100k 10 part count limit from the v8 installation.
After using it to test V9 generated parts and configurations during the last 2 days, I am confident enough to recommend to those using Xpress as a reader, that they can upgrade their customers using Xpress. Try it for yourself to make sure, but I am not waiting for the official release of Xpress 9.
I would install Xpress, and register before upgrading to v9. I have not tried a v9 xpress installation on a machine without Xpress 8 as I have run out of DirectX 9 supported machines (and tried the patience of my grandson who gets bumped off his computer for my testing).
A note on Configuration functionality: While standard and Xpress users can not modify the features in any configuration other than the current/saved configuration; changes CAN be made to the unmodifiable configurations via the equation editor. For a simple rectangular feature, the Width, Length, Thickness/depth can be changed by changing the values in the equation editor. So you can modify the dimensions driving a feature as long as there is an entry in the equation editor, and you have left paramater values unlocked for that configuration when it was saved.
