When building my PC with an SSD, I relocated /users to a hard drive with drive letter y: (so that temporary drive allocation would not impact). The lazy guide to do this involved creating some symbolic links and stuff.

I would now like to upgrade to Windows 8. Will it work?
I saw some guides on relocating when installing, but it's not exactly the same.

If the upgrade assistant crams everything on my SSD i won't work, it's too small.
