There are three ways in which to upgrade to VMware vSphere, these are
- VMware Update Manager
- vSphere Host Update Utility 4.0, and
- a clean install of vSphere
This post goes through the upgrade process using the vSphere Host Update Utility 4.0. A 10 minute video is available here:
The vSphere Host Update Utility 4.0 is an application that is installed as part of the vSphere vCenter installation package.
- To start the upgrade process, launch the vSphere Host Update Utility.
- The vSphere Host Update Utility will request confirmation to connect to the VMware patch repository.
- Add the host to the update utility by clicking on Host | Add Host.
- Type in the FQDN or IP address of the host you wish to upgrade then click on Add.
- Now click on the Upgrade button to start the upgrade wizard.
- Next browse to the location of your vSphere ISO file then click on Next.
- Read and accept the license agreement to continue.
- Enter the root credentials then press Next.
- The Host compatibility check will perform some checks and will allow the upgrade to continue if the host meets the criteria.
- Next select a local datastore (recommended) to store the disk file for the Console OS and also select the disk size.
- Leave all other settings on default and finish the Wizard
- Once complete, reconnect the host in vCenter to install the new vCenter Agent.
