I think you shouldn't even try to update to 5.0 without doing a full factory reset after installing the update. I did it with my Nexus 5 and Lollipop restored all my apps and homescreens, except for the apps that were from outside the Play Store. Not a big hassle and the phone is running perfectly.
I see all the complaints about 5.0, but what I want to know is how many people are having problems with 5.0 after doing a factory reset on their Nexus 7 2012? I may decide to hold off till 5.1.
