As many begin the process of upgrading their ESXi software to the latest version, there are a variety of steps to be aware of. In this tutorial article, I'll explain how to upgrade ESXi 5.1 to ESXi 6.0 in 5 easy steps.   

Before we get started:
It is important to ensure you have valid backups of your virtual machines before you make any changes to a Production VMware vSphere Hypervisor ESXi 5.1 Host server, which is hosting virtual machines. Additionally, all virtual machines must be powered off and the server should be in maintenance mode.

Here are the steps to upgrade your software:

  1. Download the ESXi 6.0 Offline Bundle from VMware - here
 
2. Upload the offline bundle to an ESXi 5.1 datastore
 
3. Connect to the ESXi 5.1 host server via SSH

  • At the console prompt, type vmware -l to confirm the ESXi version. VMware ESXi 5.1.0 GA or later should be returned, though this will depend upon whether any patches that have been applied.
 
4. Use esxcli at the console command line to upgrade the server
  • At the console, type the following:

ESXi-5.1.0-GA.jpg

esxcli software vib update -d /vmfs/volumes/datastore1/VMware-ESXi-6.0.0-2494585-depot.zip
 
  • The above command does not produce any feedback if entered correctly. After approximately 20 seconds, the upgrade should be complete. However, we have found if you are using slow USB flash drives and SD cards, this can take considerably longer for the files to be written. Once it is complete, you will be presented with the following screen:

  • If all is well, you should see an update screen, shown above, though you may have to scroll the screen to see all the information. Check the update result at the top.If the update completed successfully, the system needs to be reboot for the changes to be effective.
  • You can see new VIB packages (driver packages) installed, removed, and none that were skipped. If you are using an OEM version of VMware ESXi 5.1 (e.g. from HP, IBM or Dell), your output could be different.

  • Type "reboot" to reboot the server.
 
5. Check the ESXi 5.1 Host server has been upgraded
  • Check the following:
    • The Console Screen should report VMware ESXi 6.0.0 (VMKernel Release Build 2809209)

Congratulations, you have successfully upgraded your host server from VMware ESXi 5.1 to VMware ESXi 6.0.

Basic VMware Articles Series:  During this series of articles, VMware released VMware vSphere 5.5 and VMware vSphere Hypervisor ESXi 5.5. These articles are also applicable to VMware vSphere Hypervisor ESXi 5.0 and 5.5. For consistency, I have used VMware vSphere Hypervisor ESXi 5.1 throughout this series:

When I download the offline bundle it is in zip format.  Do I have to create an ISO or just upload the zip file in the datastore and the run the cli command to upgrade?

@Thanks for your update, Link was correct at time of publishing, links change all the time, when VMware change their website, and this article has been superseded by newer articles.

Thanks for the link.

I've checked the link, and it still goes to VMware. You do need to be logged into VMware!
