About This Book

The vSphere Upgrade Guide describes how to upgrade from earlier versions of VMware® ESX™, ESXi, and

VMware vCenter™ Server to ESX 4.0/ESXi 4.0 and vCenter Server 4.0.

This guide includes the following tasks:

nUpgrade to vCenter Server 4.0.

nInstall vCenter Server 4.0 on a different machine and keep the VirtualCenter 2.x database. You would do

this if you are upgrading from a 32-bit server to a 64-bit server, for example.

nUpgrade to ESX 4.0 from ESX 3.x.

nUpgrade to ESXi 4.0 from ESXi 3.5.

nUpgrade to ESX 4.0 from ESX 2.5.x using upgrade VMotion.

nUpgrade to ESX 4.0 from ESX 2.5.x using cold migration.

nChange ESX to ESXi and the reverse.

nUpgrade VMware Tools and virtual hardware.

To learn how to simplify and automate your datacenter upgrade, see the vCenter Update Manager Administration

Guide.

If you have legacy versions of ESX, ESXi, and VirtualCenter, and you want to migrate to

VMware vsphere™ 4.0 by performing fresh installations that do not preserve existing data, see the following

manuals:

nESX and vCenter Server Installation Guide

nESXi Installable and vCenter Server Setup Guide

nESXi Embedded and vCenter Server Setup Guide

Intended Audience

This book is intended for anyone who needs to upgrade from earlier versions of ESX/ESXi and vCenter Server

to ESX 4.0/ESXi 4.0 and vCenter Server 4.0. The information in this manual is written for experienced Microsoft

Windows or Linux system administrators who are familiar with virtual machine technology and datacenter

operations.
