Upgrade vCenter Server to version 5.5. See Chapter 4, “Upgrading vCenter Server,” on page 61.

Install the version 5.5 vSphere Web Client. See “Install or Upgrade the vSphere Web Client,” on

page 128.

If your environment has vCenter Update Manager, upgrade it to the latest version.

Procedure

1 Add the ESXi 5.5 host to vCenter Server 5.5.

2 Add the ESX 4.x/ESXi 4.x hosts to vCenter Server 5.5.

3 Power off or suspend the virtual machines on the ESX 4.x/ESXi 4.x hosts.

4 Move the virtual machines to the ESXi 5.5 host.

What to do next

For all hosts and virtual machines in the migration upgrade, take the following actions.

Upgrade your virtual machines. See Chapter 8, “Upgrading Virtual Machines and VMware Tools,” on

page 215.

Upgrade your product licenses:

a Get your new license keys by email, or by using the license portal.

b Apply the new license keys to your assets using the vSphere Web Client.

Migrating ESX 4.x or ESXi 4.x Hosts to ESXi 5.5 in a PXE-Booted Auto

Deploy Installation

This high-level overview describes the process for migrating an ESX/ESXi 4.x host to an ESXi 5.5 installation

that is deployed by using vSphere Auto Deploy.

This scenario assumes the following details about your vSphere environment.

The hosts that you are migrating are managed by a vCenter Server running vCenter Server 4.x.

All hosts managed by that vCenter Server are running ESX/ESXi 4.x.

The following tasks provide an overview of the migration process.

1 Create host profiles for the ESXi 4.x hosts to be migrated and attach the host profiles to the hosts.

See the vSphere Host Profiles documentation.

2 Upgrade the 4.x vCenter Server to version 5.5.

See Chapter 4, “Upgrading vCenter Server,” on page 61.

3 Prepare your Auto Deploy server and environment.

This preparation includes setting up the DHCP and TFTP servers that are used to PXE-boot Auto

Deploy host machines and installing VMware PowerCLI.

See the information about preparing for vSphere Auto Deploy in the vSphere Installation and Setup

documentation.

4 Apply an image profile for an ESXI 5.5 host that is deployed by using the Auto Deploy PowerCLI

commands.

See the information about Auto Deploy in the vSphere Installation and Setup documentation.

5 Use vSphere vMotion to evacuate all virtual machines from the hosts to be migrated, and place the

hosts in maintenance mode.

See the vCenter Server and Host Management documentation.
