I have a Magento 1 website with a bunch of legacy websites (stores) which haven't been used for years but which still contain a bunch of old products/settings/etc.
I'm migrating to Magento 2 but don't want to migrate the old stores.
What's the best way to exclude these old stores and only migrate the store(s) I need?
Obviously I would want to exclude not only the store data itself but all of the product associations and store-specific settings related to the old stores.
