Perhaps now would be a good time for IBM to release a tutorial for the pre-5.2 -> 5.2+ migrations. Lots of real-life examples and examples of migration from oldder network architectures to the new GuestLans/Vswitch architectures and then onto the VLAN stuff. Please remember that most of the VM audience now are NOT TCPIP GURUs. Explanations, pictures and lots of r eal examples will help pass your knowledge onto us.
