I'm going to level up all instance types instead.

[adriaanm]

FYI, I just fixed this with knife cookbook delete compat_resource :-) No idea where that cookbook came from?

[SethTisue]

the leveling up of instance types is postponed

(the deploy step can wait until the next time we're doing something else)
