Prerequisites for the vCenter Server Upgrade

Before you begin the upgrade to vCenter Server, make sure you prepare the vCenter Server system and the

database.

Prerequisites for Understanding and Preparing for the Upgrade Process

vCenter Server 5.5 requires vCenter Single Sign-On and Inventory Service. Install or update these

components in this order: vCenter Single Sign-On, the vSphere Web Client, Inventory Service, and

vCenter Server. Review the topics in the section “How vCenter Single Sign-On Affects vCenter Server

Upgrades,” on page 32

Review the release notes for known issues or special installation notes.

Gather the information that is required to complete the installation wizard. See “Required Information

for Installing or Upgrading vCenter Single Sign-On, Inventory Service, vCenter Server, and the vSphere

Web Client,” on page 41.

Download the vCenter Server installer from the VMware Web site.

System Prerequisites

Verify that your system meets the requirements listed in “Hardware Requirements for vCenter Server,

the vSphere Web Client, vCenter Inventory Service, and vCenter Single Sign-On,” on page 17 and

“vCenter Server Software Requirements,” on page 22, and that the required ports are open, as discussed

in “Required Ports for vCenter Server,” on page 23.

If your vSphere system includes VMware solutions or plug-ins, make sure they are compatible with the

vCenter Server version that you are upgrading to. See the VMware Product Interoperability Matrix at

http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.

Before you upgrade any vCenter Server that belongs to a Linked Mode group, remove it from the

Linked Mode group. Upgrading vCenter Servers that are members of a Linked Mode group can cause

the upgrade to fail, and can leave vCenter Servers in an unusable state. After you upgrade all members

of a Linked Mode group to version 5.5, you can rejoin them.

If you do not intend to use evaluation mode, make sure that you have valid license keys for all

purchased functionality. License keys from vSphere versions prior to version 5.0 are not supported in

vCenter Server 5.x. If you do not have the license key, you can install in evaluation mode and use the

vSphere Web Client to enter the license key later.

Close all instances of the vSphere Web Client.

Verify that the system on which you are upgrading vCenter Server is not an Active Directory primary

or backup domain controller.

Either remove any ESX Server 2.x or 3.x hosts from the vCenter Server inventory or upgrade these hosts

to version 4.0 or later.

Update any ESX/ESXi 4.1 hosts to version 4.1 Update 1 or later. See Knowledge Base article 2009586.

Before you install or upgrade any vSphere product, synchronize the clocks of all machines on the

vSphere network. See “Synchronizing Clocks on the vSphere Network,” on page 53.

Verify that the fully qualified domain name (FQDN) of the system where you will upgrade vCenter

Server is resolvable. To check that the FQDN is resolvable, type nslookup your_vCenter_Server_fqdn at

a command line prompt. If the FQDN is resolvable, the nslookup command returns the IP and name of

the domain controller machine.

Run the vCenter Host Agent Pre-Upgrade Checker.
