Few preinstall questions

I am trying to understand this product. Excuse me if the questions are silly but I don’t see it in description (english barrier).

Scenario:

Old website, woocommerce, 26 products, 2500 users and 300 orders.
New website: clean state. WordPress with woocommerce. Only 1 user (admin). All products recreated from scratch (so they have new IDs which is different to old website)

1. If I export users from a website running woocommerce into a new website with woocommerce are their login and password retained? Like they don’t need to receive email with new credentials or something like that? They can simply login as before? Basically your product will export and import their profiles with username and passwords?

2. Is it possible that their order history (meta data) is exported and then reimported even though on new website products are with different IDs. I am asking this only for users being able to see through their order history. It is actually not important if product links in their order history don’t work correctly.

3. Can I do this “silently” without them receiving any emails about it. Let’s imagine that I have a new website ready to go, I just want to publish it and allow them to login as before and see their order history. That’s all to it.
