This is the preferred method for upgrading ESXi hosts managed by vCenter and allows you to upgrade multiple ESXi hosts at once by using the same image. VMware Lifecycle Manager for VMware vSphere 7.0 is a modified VMware Update Manager that was used in vSphere 6.7. This method is applicable only for ESXi hosts managed by vCenter Server. This method can be used for VMware ESXi 6.7 to 7.0 upgrade for standalone ESXi hosts and ESXi hosts managed by vCenter.

Upgrade by using ESXCLI, the command line interface.

This blog post covers two main methods for a VMware ESXi upgrade: If there are any VMware add-ons or plugins installed, check their compatibility by using the VMware Compatibility Matrix. Follow this vSphere upgrade order, otherwise you can lose the connection between an ESXi host and vCenter. Thus, you have to upgrade vCenter first and then go to ESXi upgrade if you want to upgrade vSphere 6.7 to 7.0. 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.
