What the exit costs before the arrival does, which four kinds of record survive the move and which one never transfers anywhere, and the three questions that decide it. Two practices, two different answers.
What comes across and what does not, what breaks quietly, and the four situations where staying is the better call. Written from migrations we have carried out record by record.
Four of them, and two cost nothing. The arithmetic that tells you whether moving is actually cheaper, and what to do when the rise is justified by AI features you did not ask for.
