Let me be more specific with my question. I have already done this once and I think what Browni says is not correct. When I turned on the new machine it asked if I had files I would like to transfer over from another machine. I said yes, used f/w cable and got all the info over just fine, BUT it made ME the administrator of my daughter's machine. I could add her as another administrator, but we both would like her machine to have only one user, herself. Also, her entire I-tunes library was under my account and when we added her as an administrator she had NOTHING in her Itunes library. True, we could make this Shared, but we were hoping to get me off it entirely. So we scrubbed the machine and are starting over.
If I do what the other post says, i.e. change target direction, then I would need to physically take everything over one by one because there is nothing to transfer going the other way. I could do it physically because you see the other machine but I am not sure where everything is, including librarys, etc.
I thought there was a way to put in the user FIRST, before you transfered over.
