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
