If both servers are at Version 3 you could use server to server facilities to
export client data from OS/390 to virtual volumes on AIX and then import from
the virtual volumes to the AIX server itself. This approach is discussed in
detail in a pre-publication version of an IBM Redbook. I found this at:

  http://www.redbooks.ibm.com/SG245244/sg245207.html#HDRIMPEXP

You might be able to export on OS/390 to a device class with the FILE device
type, use FTP to transfer the resulting disk files to AIX, and import from a
device class with the FILE device type. I don't know of anyone who has done
that, and I am not at all sure it would work. It might, for example, fail
because of different treatment of record boundaries under the two operating
systems.
