It’s quite simple to download the ESXi installation media from VMware. The installer also gives you the option to migrate some existing host settings and configuration files and to preserve the existing VMFS datastore.” The installer works the same as for a fresh installation, but if you select a target disk that already contains an ESXi installation, the installer upgrades the host to 6.7. This method is appropriate for deployments with a small number of hosts. You can run the ESXi 6.7 installer from a CD/DVD or USB flash drive to do an interactive upgrade. “Upgrade interactively by using an ESXi installer ISO image on CD/DVD or USB flash drive.
#Building a home lab for vmware vsphere 6.5 upgrade
The following paragraph is taken from VMware which details more information about the ‘GUI’ upgrade method. Sometimes this is referred to as the ‘interactive’ method. In my instance, I’ll be upgrading using the ‘GUI’ method. So there are a few different methods for upgrading ESXi hosts. Specifically for my case, I’ll be upgrading from VMware ESXi 6.5.0 (build 5969303) to VMware ESXi 6.7 (build 15160138). The version of ESXi is a bit old and overdue for an upgrade so I thought this would be a good opportunity to document the process for anyone else interested in the ESXi upgrade process. At one point the server even hosted this very blog for over 3 years. I built the server back in 2013 and to date, the server has been rock solid. While my homelab can’t run dozens of virtual machines concurrently, it’s power-efficient, cheap and importantly quiet. My homelab compute consists of a single server with an i7-3770 CPU / 32GB DDR3 RAM / 1TB SSD connected to an Intel BOXDQ77MK motherboard, basically a glorified PC. To check if all installed NICs have been enabled, from the VMware Host Client select. Part of this transition was to create an ESXi ISO with the latest build 6.7U3. This might cause ESXi hosts to fail with a purple diagnostic screen.
As with most IT enthusiasts, I use a homelab for tinkering, troubleshooting and hopefully a bit of learning. I ran into the MiniPC the VMware ISO with Realtek drivers.
