How to upgrade to vSphere 5.5
A few weeks ago during VMworld 2013 VMware announced vSphere 5.5. We already did a ‘What’s new in vSphere 5.5‘ post but now it is actually available, so it’s time to find out how to upgrade to vSphere 5.5.
But before we start, there are a few caveats:
- ESXi 5.0 and 5.1 included drivers for network adapters that are not officially supported by VMware, but were very useful for installing ESXi on whitebox hardware. Some of these drivers have been removed, e.g. net-r8168 and net-r8169 for certain Realtek adapters and net-sky2 for Marvell adapters;
- Once you upgrade a virtual machine’s hardware to VM hardware version 10, it is no longer possible to edit the virtual machine using the traditional vSphere client. Modification to this virtual machine must be executed using the vSphere Web Client. This can be a problem when you are using a free version of ESXi or if you’re unable to manage it through a vCenter server for whatever reason.
Because I run a VMware vSphere 5.1 environment, this is a upgrade from vSphere 5.1 to 5.5.
The upgrade is a straight forward four step process.
