Upgrade Vmware vSphere from 5.1 to 5.5 – Step 6 – ESXI upgrade

After everything has been upgraded to 5.5, we can now upgrade ESXI host to 5.5.

In order to do this, connect to your vSphere Client now and open Update Manager in Home Menu. If doesn’t there, that means you haven’t installed Update Manager client.

In vSphere Client, in the menu, open Plug-ins and choose Update Manager Client 5.5 and click on “Download and install ” link.

When the installation is finished go to Home again and look the bottom. You will see Update manager now.

Open Update Manager and go to ESXI Images tab. Select Import ESXI Images.

Yes I would like to create a Baseline which I will use it when I upgrade the ESXI host

What I did before the screen below is that I moved the all servers manually to another host. Now the host I want to upgrade has no any VMs now.

Click on ESXI host name and go to Update Manager tab. Click on Attach button

Choose the Baseline you created above and click on “Attach”

Now you can click on Remediate now and the upgrade process will be started.

Actually, you see 1-Details is yellow. Basically, before the upgrade, I must reboot the service.

This is the reason why I have yellow warning. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2034945

After the reboot is completed, I clicked on Remediate button
