While VMware offers a number of different upgrade strategies for the vSphere Hypervisor, the following interactive update process is suitable for any Cisco Business Edition server deployment and can be carried out either locally or remotely.
To carry out this upgrade process, you require the following:
HTTP access to the Business Edition Server Integrated Management Console (CIMC).
Access to the vSphere Hypervisor using the VMware vSphere client running on a Microsoft Windows operating system.
If upgrading the hypervisor remotely, ensure that sufficient bandwidth is available to download and upload the hypervisor install file (approximately 300 MB).
Download the custom Cisco ESXi Virtualization Hypervisor installation ISO package from your Cisco Electronic software delivery account (edelivery.cisco.com/esd). Alternatively, register for a free My VMware account to access software from the following URLs:
As common licenses are used for ESXi 5.x software releases, you do not have to upgrade licenses when upgrading between ESXi 5.0, ESXi 5.1, or ESXi 5.5.
