Can’t Import Users

I am currently testing my community site with Ultimate Member plugin. I have exported the Users using WP Export All plugin from Site 1. Now I am trying to import using WP All Import to Site 2 but after importing users, the members directory (Members page) on Site 2 is not showing users.

I am currently testing of what will happen if my website goes off or anything so how will I make the community with Ultimate Member again on a new wordpress installation with all my users data intact and Members Directory recovered. My community is big minimum 10 thousand members.

Please help.
