Since vSphere 7 has been out for a while, I figured it would be good to do a quick blog post on how to upgrade vSphere. I was currently running 6.7, and wanted to check out the process of upgrading using my existing VCSA. This upgrade is not like typical upgrades where you download a package and upgrade the software using the existing installation; rather, the VCSA process is a bit different in that each “upgrade” is a new deployment of the VCSA, and a migration of the data from the existing VCSA to the newly deployed VCSA. Fortunately, VMWare has made this process extremely easy. I have found this process to be very reliable as well. In essence, a new VM is deployed and a new VCSA is provisioned on using another IP. Then everything is migrated and the original VCSA is powered down. That’s pretty much it. Now, lets take a moment and see how the process unfolds step by step.
Performing the Deployment/Upgrade/Migration Process
First, download the installed from VMware. Since I am using windows, once I have finished downloading the installer ISO, I headed to the directory \vcsa-ui-installer\win3 and ran this as administrator.
Please note: vSphere 7.0 disables TLS 1.0 and 1.1, so ensure you have no dependencies that require this.
