General Steps
Upgrade View Connection Servers to Version 4
Upgrade View Composer to Version 2
Upgrade vCenter and ESX to vSphere 4 Update 1 if needed
Upgrade View Agents to Version 4
Upgrade View Clients to Version 4
Recompose

View Connection Server Requirements
2.0 GHz or higher – Dual Processors
2GB of RAM – 3GB RAM for 50 or more desktops
One 10/100 NIC – 1GBE (w/redundancy)
Do not install on a DC
Only on Windows 2003 Server (Standard/Enterprise) with/without R2 and with SP2 (not supported on Windows Server 2008)
Valid license key – 25 character
Local admin permissions for both VCS and View Composer
Administrative credentials for vCenter Server
Only on vSphere with Update 1, VI 3.0.2 and VI 3.5 Update 3 required (Update 4 recommended)
Windows 2008 AD is now supported

View Composer System Requirements
VI 3.5 Update 3 or 4
vSphere4 Update 1
vCenter Server 4.0 Update 1
vCenter Server 2.5
Windows 2003 SP1 or higher
Database requirements – MS SQL2000, Oracle 9i, 10g are not supported due to losing support on vSphere
Browser requirements – IE7, IE8, Firefox 3.0 and Firefox 3.5 are supported

Preparing View Connection Server for Upgrade
* Verify system requirements
* Take a snap shot of View Connection Servers running as VMs
* Document all View Manager and Desktop Pool settings
* Backup the View Manager ADAM database
* Verify that any custom scripts have been tested against View 4
Preparing View Composer/vCenter Server for Upgrade
* verify system requirements
* if vCenter is running in a VM, take a snapshot
* computer name is longer than 15 characters, rename with a shorter name
* Backup vCenter Database
Upgrade Process

Maintenance Window 1
Connection Servers, Security Servers and View Composer

Maintenance Window 2
vCenter and ESX

Maintenance Window 3
Recompose Pools or Upgrade View Desktop Pools
Upgrade View Clients
Upgrade Thin client BIOS
Upgrade Thin clients

View Connection Server Upgrade
Stop View Connection Server service on all the Servers
Run the installer – ADAM DB is updated – perform on each of the servers
Verify the VMware View connection server service restarted after the installation routine
Use vdmexport.exe (version 4) to backup the newly upgraded ADAM database
Import the updated GPO templates into AD (optional – only if GPOs are in use)
Upgrade the remaining CS in the ADAM replication group
Verify connectivity to each CS in the replication group
Upgrade the Security Servers
Import View 4 updated GPO templates into AD

View Composer/vCenter upgrade
Verify that you have a valid View 4 license key
Run the View composer installer on vCenter Server
When prompted for View Composer port number, use 18443
(vcenter Server 4 uses port 8443)
Uninstall the View Agent in a test Parent VM, and deploy a test pool from this parent
Test automatic deployment and connectivity with this pool
Upgrade Virtual Center 2.5 to vCenter 4.0 Update 1
(verify desktop deployment and connectivity in the test pool again)

Upgrade ESX hosts and VMs
Verify the vCenter server upgrade is complete
Upgrade ESX servers by clusters that match to desktop pools
(when all hosts within a cluster for a given pool, you can turn  on vSphere compatibility mode for View Composer)
Upgrade the VMware tools, the VM hardware and View Agent in all Parent VMs
(the vSphere update manager can upgrade the VMware tools and virtual hardware)

Upgrade View Desktop pools and View clients

For non-persistent pools, you simply recreate the desktop pool and de-entitle the former pool
for persistent pools, recompose the pool, pointing to a new snapshot of the parent VM with the updated VMware tools, hardware and View Agent.
One the pools are updated, update the View Client software

Other Points

Corrupting ADAM database is very high, so be careful during the process
Windows 7 is experimentally supported
A dedicated “VMware View Upgrade Document” is coming out soon

I am not trying to duplicate anything here, but this is a quick, dirty and handy list of requirements for VDI components:

VMware View 4
* 32-bit or 64-bit dedicated physical or virtual server:
* Pentium IV 2.0GHz – dual processors
* 4GB RAM
* 20GB Disk Space
* 1Gbps NIC
* OS – Windows 2003 or Windows 2003 R2 – Standard/Enterprise with SP2
* License for View Manager with View Composer and Offline Desktop
* View Connection Server Host OS should be joined to AD Domain
* Windows AD 2000, 2003 and 2008 are supported
* View Agent (installed on both Physical or Virtual), View Client, Offline Desktop and View Composer all can run only on 32-bit OS
View Composer 2
* View Composer only on 32-bit – so your vCenter Server should be running on a 32-bit OS not 64-bit
* At least vCenter 2.5 Update 3 or 4
* ESX/ESXi 3.5 Update 3 or 4
* vCenter 2.0.2 or higher without View Composer
* Installed prior to View Connection Servers if linked cloned VMs are provisioned
* ODBC data source to the View Composer Database
* The prepackaged SQL Server 2005 does not include any management tools for the database.  In order to create a new database instance for View Composer, you will need to install SQL Server Management Studio Express.  This can be downloaded from the Microsoft download center website by searching for “SQLServer2005_SSMSEE.msi”.
ESX
* vSphere4 Update 1 (Offline Desktop is not supported on vSphere 4)or
* ESX 3.5 Update 3 or Update 4 (but not Update 5)
* ESX 3.0.2 (View Composer is not supported on ESX 3.0.2)
vCenter
* Sysprep tools must be installed on the vCenter Server, in order to apply customization specifications to standard (non-linked c
