Windows 7 Evaluation Copy Build 7100 upgrade to Pro possible?

Hey guys,

I have the Windows 7 Evaluation copy installed right now on my computer and it's telling me that it's already expiring... i actually put the date on my computer back so i have a few more days to spare... a few questions now...

1. What happens when it's expired? Will I not be able to turn on my computer?

2. Is it possible in any way to upgrade from Windows 7 Ultimate Evaluation to Windows 7 Professional without needing to wipe out all my programs and data from C: drive?
