Before upgrading, consider disconnecting your network storage. This action decreases the time it takes the

installer to search for available disk drives. When you disconnect network storage, any files on the

disconnected disks are unavailable at installation. Do not disconnect a LUN that contains an existing ESX or

ESXi installation. Do not disconnect a VMFS datastore that contains the Service Console of an existing ESX

installation. These actions can affect the outcome of the installation.

IMPORTANT After you upgrade or migrate your host to ESXi 5.x, you cannot roll back to your version 4.x

ESX or ESXi software. Back up your host before you perform an upgrade or migration, so that, if the

upgrade or migration fails, you can restore your 4.x host.

Prerequisites

You must have the ESXi installer ISO in one of the following locations.

On CD or DVD. If you do not have the installation CD/DVD, you can create one. See “Download

and Burn the ESXi Installer ISO Image to a CD or DVD,” on page 154

On a USB flash drive. See “Format a USB Flash Drive to Boot the ESXi Installation or Upgrade,” on

page 155

NOTE You can also PXE boot the ESXi installer to launch an interactive installation or a scripted

installation. See “PXE Booting the ESXi Installer,” on page 158.

Verify that the server hardware clock is set to UTC. This setting is in the system BIOS.

ESXi Embedded must not be on the host. ESXi Installable and ESXi Embedded cannot exist on the same

host.

Procedure

1 Insert the ESXi installer CD/DVD into the CD/DVD-ROM drive, or attach the Installer USB flash drive

and restart the machine.

2 Set the BIOS to boot from the CD-ROM device or the USB flash drive.

See your hardware vendor documentation for information on changing boot order.

3 In the Select a Disk panel, select the drive on which to install or upgrade ESXi and press Enter.

Press F1 for information about the selected disk.

NOTE Do not rely on the disk order in the list to select a disk. The disk order is determined by the

BIOS. On systems where drives are continuously being added and removed, they might be out of order.

4 If the installer finds an existing ESX or ESXi installation and VMFS datastore you can choose from the

following options:

Upgrade ESXi, preserve VMFS datastore

Install ESXi, preserve VMFS datastore

Install ESXi, overwrite VMFS datastore

If an existing VMFS datastore cannot be preserved, you can choose only to install ESXi and overwrite

the existing VMFS datastore, or to cancel the installation. If you choose to overwrite the existing VMFS

datastore, back up the datastore first.
