Being new to the toolbox, I can't help noticing that apparently some work is spent on raising old dust. Lately I've seen migrations of posts from 2009 ([1][1], [2][2]) to SuperUser despite of the apparent consensus that legacy posts are not to be migrated.

Although I am all in favor of the "rules are there so you *think* before you break them" philosophy, I fail to see a straight line here. From what I have read on meta so far, I understand the guiding principle to be not to touch old questions for migration if they have been answered here. Am I mistaken? Are there somewhat more concise guidelines or is it something to be decided "with the gut" and mainly done whenever one stumbles over off-topic posts?
