So today I wanted to update my old Dell T7910 Lab machine to 8.0U3i. It was running a pretty old build (ESXi 8.0U1) from 2023 so I checked the interoperability matrix for ESXi first to make sure the upgrade path was supported and great news, it is, so lets proceed. Download the patch file In the Broadcom Portal, navigate to https://support.broadcom.com/group/ecx/downloads , select VMware vSphere > Solutions > VMware vSphere Enterprise Plus > 8.0 > VMware-ESXi-8.0U3i-25205845
