migrating users from TD14.10 to TD15

Hi,

In my server I am running TD Express for VMware, version TD14.10. I have created several users and have no relevant data there (its a sort of sandbox for some users).

I would like to create all the users and keep the same passwords. I am guessing that this could be done exporting and loading some tables into TD15?

Is there any document that could help me with this?

Thanks!
