You can upgrade an ESXi host with version 6.5 or 6.7 by using an interactive upgrade from a CD, DVD/USB/Virtual Media or ISO Mapped with iLO/iDRAC, vSphere Lifecycle Manager (baselines) and ESXCLI Command Line.

Consider disconnecting the network storage before upgrading. By doing this, the installer can find available disc drives more quickly. Any files on the disconnected discs are unavailable at installation when network storage is disconnected. Never unplug a LUN containing an active ESXi installation.

  • Download and Upload required iso image in datastore.

Use the cd command to open the folder where the iso image is stored.

cd /vmfs/volumes/ISO-Images

Display the list of available profiles in the image.

esxcli software sources profile list -d /vmfs/volumes/601ba49d-da4c2c34-e1ec-8e8559d00159/VMware-VMvisor-Installer-7.0.0.update03-20328353.x86_64-Dell_Customized-A09.zip

In our example, there is only one profile: DEL-ESXi-703_20328353-A09

You can use the –dry-run option to preview the results of an installation or upgrade operation.

esxcli software profile update -d /vmfs/volumes/601ba49d-da4c2c34-e1ec-8e8559d00159/VMware-VMvisor-Installer-7.0.0.update03-20328353.x86_64-Dell_Customized-A09.zip -p DEL-ESXi-703_20328353-A09 --dry-run

Upgrade the ESXi version using the selected profile.

esxcli software profile update -d /vmfs/volumes/601ba49d-da4c2c34-e1ec-8e8559d00159/VMware-VMvisor-Installer-7.0.0.update03-20328353.x86_64-Dell_Customized-A09.zip -p DEL-ESXi-703_20328353-A09 --no-sig-check
