Upgrading an ESX host(i) 4.x a ESXi 5 manually

In this document we will look at one of the ways to update our ESXi 4.x hosts (we could also migrate from ESX 4.x to ESXi 5.0 and ESX(i) 3.5 to ESXi 5), it will be in a manual/interactive way by entering the ESXi cd/dvd/usb 5.0 on the ESX host itself(i) 4.x. This is one of the simplest ways for smaller environments, In future documents we will see other forms of updates. Prior to the upgrade we will have verified that our hosts support the new hypervisor using Agent Pre-upgrade check,

vCenter Host Agent Pre-Upgrade Checker

Before updating our VMware vSphere infrastructure to VMware vSphere version 5 (our hosts to ESXi 5.0) we must run a utility available on the VMware vSphere DVD 5, where we can verify without service interruptions if our ESXi hosts are compatible for a potential version upgrade (from VMware ESXi 4.x to VMware ESXi 5.0) thanks to the vCenter Agent Pre-upgrade Check tool.

Upgrading from VMware ESX 4.0 to ESX 4.1 manually

If we intend to upgrade our VMware ESX hosts 4.0 or VMware ESXi 4.0 to the new version of vSphere 4.1 manually, This is, without using VMware Update Manager we can do it in a simple way. We will only have to download a couple of files, copy them to the host and apply them to update the computer, Previously we will have shut down all the virtual machines that the host runs or we have moved them to other computers and put the computer in maintenance mode.
