License Server Scenarios
If you upgrade to vCenter Server 4.0 and you want the vCenter Server system to manage ESX 3.x/ESXi 3.5
hosts, you might need to verify that the license server is running and reconfigure vCenter Server 4.0 to point
to the license server, depending on your upgrade scenario.
Table 8-1 lists the license server scenarios and the necessary actions.
