Well, I am using CM11 now.
I initially tried a few times to install it with a full wipe of Cache, Dalvic Cache, System, and Data.
However, the Play Store would not automatically reinstall my apps.
Even worse, while installing the apps I would eventually get an error 920 - which would prompt me to wipe and reinstall again.
I finally just dirty flashed CM11 on top of CM10.2 and everything appears to be working OK - so far.
