Export joomla user with same password

I am merging a small group on sort of site with my joomla site. I already have members in my joomla site so I somehow want to migrate the users of joomla to groupon database which uses a differen开发者_StackOverflow社区t encryption scheme for password. Is there a way to do that?

You would have to have the unencrypted passwords to be able to use that. There is no conversion from one encryption scheme to another.
