Best 3 ways to upgrade ESXI host

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.

1. Upgrade ESXI host with CD, DVD/USB or ISO Mapped with iLO/iDRAC:

You can boot the ESXi installer from a CD, DVD, or USB flash drive to upgrade ESXi host.

2. Upgrade ESXI host with vSphere Lifecycle Manager (Baselines):

You can create upgrade baselines for ESXi hosts with ESXi images, wchich you import to the Update Manager repository.

3. Upgrade ESXI host with ESXCLI Command Line:

Make sure SSH service is enabled before upgrading the server using the CLI; otherwise, putty won’t be able to connect to the server.

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/

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/ -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/ -p DEL-ESXi-703_20328353-A09 --no-sig-check
