Terrifyingly vague

Every time I use this, and I’ve used it a dozen times or more, I have to double and triple check which site is the source and which site is the destination. The documentation does not make it clear, and it’s easy to make a mistake. Getting it wrong will wipe your existing site and replace it with the blank site you’re attempting to migrate it to. There’s no reason why they are unable to explain their own product in plain English, using simple words like FROM and TO.
