Exporting users with passwords

I am exporting the users from the current website into the new replacement website - it won’t let me export the passwords with the users and I can see in the documentation it says that cant be done BUT then it says

For further information, please read all Import instructions, regarding Passwords.

But I dont know where that further information is?

How can I keep the users passwords in tact for the replacement website? We were hoping to go live tomorrow, but hit this stumbling block

thanks in advance

What tool are you using to export the users? This is not an s2member feature that I am aware of.
