Platform migrations, run from the inventory up.

Why migrations go wrong is always the same story. Someone moved the visible content and hoped the invisible parts — URLs, meta descriptions, structured data, redirect chains, product relationships — would sort themselves out. They never do. Every migration here is scoped backwards: list everything the current site has, decide item by item where it lands, write the redirect map, then move. Slower to start, boring to launch. The general migration service page covers the process; the pairs below cover what is specific to each move.
