[Plugin: Cimy User Manager] importing back?

Will this plugin import back users backed up with this other plugin? https://www.ads-software.com/extend/plugins/register-plus-redux-export-users/

it gathers more data in the profiles. I wonder whether it will hurt my DB or may be you know some detail. I also wrote the owner, but his site seems abandoned.

Thanks.
