Root Incredibly Re-Engineered ROM???? Installed. WT update.

[Candroid]

I just need to know if I have to do a full wipe on wife's phone to install the updated version of Re-engineered ROM. I put on v 2.00 and now v 2.20 is out. Can I just install on top of v 2.00? or should I be safe and just do a full wipe?

Thanks everybody!

Looks like the dev always recommends a full wipe. However some folks on his thread at XDA have stated they flashed over with no problem.
If you want to try it, make a nand backup, wipe dalvik (but not data) and then flash. If your phone gets wonky (sorry about the highly technical jargon) then do a complete wipe and reflash. If it gets REALLY wonky you've got a nand backup to fall back to.
