This is a follow up of#1228. I finally found some time to try to upgrade my outdated WinPython64-3.7.7.1 to newer versions.

However, after extracting the WinPython's installer, and copying my\WinPython64-3.7.7.1\settings\ to the newly extracted WinPython folder to overwrite the existing one, and after launching Spyder, no preferences of Spyder are preserved and Spyder seems to be launched with default preferences which are generated and stored inC:\Users\Username\.spyder-py3\,C:\Users\Username\.matplotlib\,C:\Users\Username\.ipython\, so in other words, the copied & pasted\WinPython64-3.7.7.1\settings\, especially Spyder-related preferences are not recognized or migrated.

More detailed steps to reproduce (I'm using Windows 10):

1. Close Spyder of WinPython64-3.7.7.1, which was previously extracted toU:\PortableApps\WinPython64-3.7.7.1\
2. Extract Winpython64-3.8.3.0.exe toU:\PortableApps\WinPython64-3.8.3.0\ (rename the extractedWPy64-3830 toWinPython64-3.8.3.0)
3. Delete the contents inU:\PortableApps\WinPython64-3.8.3.0\settings\, and copy all contents inU:\PortableApps\WinPython64-3.7.7.1\settings\ toU:\PortableApps\WinPython64-3.8.3.0\settings\, and also copy the contents inU:\PortableApps\WinPython64-3.7.7.1\notebooks\ toU:\PortableApps\WinPython64-3.8.3.0\notebooks\
4. Launch Spyder IDE of WinPython64-3.8.3.0
5. No preferences of Spyder are migrated or recognized, and default preferences are generated inC:\Users\Username\.spyder-py3\,C:\Users\Username\.matplotlib\,C:\Users\Username\.ipython\

So is this a bug? If not, how can I get Spyder's preferences properly migrated and recognized?

Many thanks.
