Creative Cloud Files - can we relocate the local Sync folder to CC prior to Sync being discontinued?

Is there a way to move the entire "Creative Cloud Files" folder that's on my local HD (the CC sync folder) over to the Creative Cloud web/app? I am not having any luck finding a way... CC won't even let me upload a single folder containing files - the upload option is grayed out unless I click on a single file. If I have to upload my files one by one (and recreate & name each folder and sub-folder), it's going to take a long time and there's a risk of missing a file.

I want to get those files copied over before Adobe discontinues the Sync option and purges the files in that folder.
