That would do it. There are a number of fundamental changes with 8.0 in particular that may not play nice if you don't give the system an opportunity to migrate your data over (via an OTA script) or start fresh (with the "-w" fastboot flash option).It's my habit to remove the "-w" fastboot option from flash-all.sh before executing it.
Next time you feel like manually updating without wiping your data, go for the OTA sideload option instead.
