The next release of vSphere ESX no longer support.
In this migration process is important, therefore, planning and knowledge I've gathered the information in 7 key points to properly prepare for this new way to manage hosts.
1) Know your enemy: differences between ESX and ESXi
It 's good to have a thorough understanding of the differences between ESX and ESXi.
The two Hypervisors run on the basis of the same VMkernel, but manage ESXi and manage different from ESX.
I recommend reading the following articles:
comparison between ESX and ESXi comparison
ESX vs.. ESXi 4.1 KnowledgeBase article
ESX and ESXi because they were very distant dedicatia very different purposes but with vSphere 4.1 several differences have been resolved
2) Increase the experience ESXi
Even if you have used ESXi, you increase your skills.
To experiment, create a soft test environment as not to impact the production environment.
If you do not have hardware advances, you can run ESXi in a vitual machine (VM) on an ESX host or VMware Workstation.
Learn the different techniques used on ESXi installandovSphere command-line interface (CLI) on your workstation and installing vSphere Management Assistant (VMA) in an ESXi host. Get used to using the vSphere PowerCLI and experience the Tech Support Mode (TSM) console either remotely or locally.
3. Find alternatives to agents and script on the ESX Service Console.
If you use agents on the ESX Service Console script and there are alternatives that work on ESXi.
There are both agents of backup hardware monitoring. Do a check with manufacturers to esserre sure that they have a technology that supports ESXi. Sometimes you will need to upgrade obsolete software.
Many agents have been included in the monitoring hardware ESXi installable through customization files that are inside the file oem.tgz file on the partition of ESXi installed please download or customizations from the hardware manufacturer's website.
If you use Perl scripts from the Service Console, you must begin to consider PowerShell, vSphere CLI or VMA.
