Switching guides

The highest-intent page on the site. Someone reading one of these has already decided to move — they want to know what it costs them and whether their history survives. 25 guides, each assembled from two records.

A guide exists where the migration has a real answer: the destination’s history-import attribute is recorded, so the page can say whether your transactions come with you or definitively do not. Destinations with that attribute Unknown get no guide until someone fills it in.
