RT dump conversion script and canned responses

Hi guys, I have two quick questions. I have to upgrade soon ( just to keep
up to date, im happy with my RT install ).
I looked everywhere and I cant find the upgrade scripts? 2.0.15 --> 3.0.2

also , i need to have the “canned reponses / stock answers” feature, is that
included in rt3?

Sorry if this stuff has been answered ad nauseum, i looked around but
couldnt find any answers.
