Migrate from VHCS2 on Server 1 to ispCP on Server 2

[DaSilva]

I have a problem with the mysql users. If I look in an account on the old server with VHCS2 then there are three different databases with different users (for example). But where the username should be is a button with "Add user" as caption (strangely all webs with mysql databases work). I think that is the reason why I have not all mysql user on the new system. So what should I do now? I have to export and import all users to the new server but I don't know how.
Thanks.
