Planning an Upgrade to VMware Infrastructure 3

Saturday, 23 September 2006 by Michel Roth

A whitepaper by VMware on planning an upgrade to VMware Infrastructure 3: Because of the breadth of the changes in VMware Infrastructure 3, environments that currently run ESX Server 2.x and VirtualCenter 1.x must be upgraded with procedures that utilize special capabilities designed into the product.

This guide aims to help IT administrators and architects understand the upgrade process and plan for it appropriately. It discusses the main changes in VMware Infrastructure that underlie the upgrade procedure as well as the principles behind the procedure. This guide describes the stages of the upgrade process itself as well as the various strategies you can use. Finally, it presents upgrade use cases to give you a view of the process from start to finish. Along the way, the guide discusses the expected downtime and repercussions of each step.

This guide is meant to provide only the information you need to determine the operational impact of an upgrade for your particular VMware ESX Server environment. For details on the actual tasks and specifics of versions and compatibility, see the VMware Infrastructure product documentation, in particular, the Installation and Upgrade Guide.
