as described above I wanted to provide more scripts and information. Here is a small script which simplifies the export and import of tables under Linux/Unix. I have always used this for system copies to make certain things easier and faster. This script can also be used by less experienced colleagues.
Generally it is nothing special, but perhaps useful for one or the other.
Download to Unix / Linux Server (tested on AIX 7.1, SLES 11 and SLES 12) and run
Select tables for the export
Select tables for import (only exported are visible)
I would be happy to hear from you if something like that is helpful or not.
