  vCenter Server Migration

This is a basic guide that I used to
 create my new vCenter server 4.0
 and migrate my ESX hosts to it.
Its not a complete guide, some areas
  not addressed are vCenter Security
  and overall setup.
This guide is for migration of ESX
 hosts and it abandons the database
 on the old Virtual Center Server.

Overview –
Old Virtual Center server 2.5
HP DL140, 2 x 80GB IDE Non-Raid, 4GB RAM, Dual CPU
