VMware vCenter 7.0 can manage ESXi 7.0, ESXi 6.7 and ESXi 6.5, but vCenter 6.7 cannot manage ESXi 7.0 hosts. If an ESXi host is managed by vCenter Server, the vCenter version must be the same or higher compared to the target version of ESXi after upgrade. There must also be enough free storage space for the ESXi upgrade.

There must be no running VMs on an ESXi host when you start the ESXi upgrade process. If an unsupported device is present (for example, an old unsupported CPU or disk controller), the ESXi upgrade will not be applied to the server. The hardware of a server running ESXi 6.7 must be compatible with ESXi 7.0, that is, it must meet the hardware requirements for ESXi 7.0.

This blog post explains how to upgrade from ESXi 6.7 to ESXi 7.0 in your vSphere environment. Otherwise, do a clean installation of ESXi 7.0. For example, upgrade first to version 6.5 and then to version 7.0. If you’re using ESXi 6.0 or earlier in your vSphere environment, you can upgrade in several steps.

You won’t have to perform a clean installation of ESXi 7.0 on servers running ESXi 6.5 or ESXi 6.7 as you can directly upgrade to v7 from these two versions. The ESXi hypervisor is one of the main vSphere components, and for a vSphere upgrade, you should perform a VMware vCenter upgrade and a VMware ESXi upgrade. VMware vSphere 7, the latest release of VMware’s virtualization platform, introduces a number of new useful features and many companies are looking forward to upgrading from vSphere 6.7 to 7.0.
