vSphere install and upgrade best practices

There has been released quite a lot of new KB articles surrounding vSphere from VMware. They also released recenly best practice guidelines for upgrade or installation to ESX 4 and vCenter 4. They are nice, brief and short, so easy to implement.

There is also a some other article which is about The best practices for upgrading an ESX 3.x virtual machine to ESX 4.0 (version 4 to version 7). Version 7 has quite a few improvements.

To upgrade your VM to the version 7 under ESX 4 you’ll have to:

01.) Upgrade VMware Tools and reboot (if necessary). – This must be done first.
02.) Shutdown the virtual machine and the upgrade virtual hardware.
03.) Power on the virtual machine. (you might need to reboot)
04.) Make sure that all the IP configuration is correct ( IP, DHCP, DNS… you might want to save this info before you run the upgrade…)
05.) If you are in DHCP run ipconfig /release and ipconfig/renew and maybe also ipconfig /registerdns just to make sure the DNS cache gets cleared.

You can do this above from each VM manualy or Inside of VMware Update Manager.
