Select the version to upgrade and start the upgrade process. The no-tools version can select in case the upgrade of the VMware tools is not required, otherwise, the standard upgrade version can be used. Now all upgradeable versions can be listed in order to determine which one will be used. Run the command: esxcli software sources profile list -d | Query VMware servers for the upgrade versions available. In order to do so, run the command: esxcli network firewall ruleset set -e true -r httpClient Since the VMware servers will be queried for the actual upgrade file, HTTP(S) outgoing connections from the ESXi server must be allowed. Modify ESXi firewall in order to allow outgoing Hyper Text Transfer Protocol (HTTP) connections. In order to do so, run the command: vim-cmd /hostsvc/maintenance_mode_enter You can use vSphere Client as shown in the image. This helps turn off any critical service that the hypervisor runs and allows the server to upgrade. Place the ESXi server in Maintenance Mode. Shutdown the virtual machines (VMs) that run on the ESXi server to be upgraded.

It is a good practice to upgrade the virtualized infrastructure to ESXi 6.0 and 6.5. VMware published the deadlines for the End of General Support and End of Technical Guidance for ESXi 5.5: If your network is live, make sure that you understand the potential impact of any command.
