Step 20:  Upgrade the ESXi hosts using Update Manager

20.1: The first step to carry out is to create a new baseline with the ESXi image. To do this go to Update Manager from the home page on the vSphere client

vCenter Upgrade Update Manager

20.11: This will kick off a scan across the entire environment.  As there are two different sites with separate Update Manager Servers the above steps will need to be carried out there also.

20.12: The next steps are to update the individual ESXi hosts to not cause any downtime. Put one of the hosts in maintenance mode and migrate any VMs from it. The host will need a reboot following the upgrade. Once the selected host is in maintenance mode select Update Manager

20.13: If you see an error about ‘host software configuration requires a reboot’. Follow the instructions and reboot the host. – http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2034945

20.25: Exit maintenance mode and migrate some VMs back onto the host. Follow the same above steps on all the remaining ESXi hosts.

 

Step 21: Upgrade DVSwitch versions

21.1: Once the ESXi hosts have been upgraded you can then upgrade any dvSwitches. Go to Networking and select the dvSwitch. Check the version number. If it’s a previous version to the current version of vCenter it will ask for an upgrade. The ESXi hosts need to be upgraded first so now is the time to upgrade the dvSwitches.

dvSwitch Upgrade Step 1

21.2: Select upgrade and select vSphere Distributed Switch Version: 5.5.0. Click Next to continue.

21.3: The hosts are checked for compatibility. Once they get the all clear click on Next.

Step 22: Upgrade VMware tools

22.1: You can view the VM Version and tools status from the top cluster view. If the tools are out-of-date they will need to be updated.

22.2: Open a console session  and select VM-> Guest -> Install/Upgrade VMware Tools.

22.4: Select Run setup when prompted

22.5: The installation will then begin. Click Next on the first dialog

Upgrade VMware Tools Step 4

22.6: Select Custom and click Next

Upgrade VMware Tools Step 5
22.7: Click Next and then click Finish to complete the install. You may be asked to reboot the server, most likely you will have to.

Congratulations!! You’ve now completed all steps of the upgrade. You can choose to upgrade the hardware version of the VMs as well. In my case it was decided due to the nature of some of the VMs the benefits they would get from the hardware upgrade it was decided to leave that upgrade component until a later date.
