Upgrading ESXi hosts and virtual machines is the most time-consuming aspect of this middle phase of a View upgrade.

About this task

This procedure provides an overview of the tasks you must perform during the second and subsequent maintenance windows. To complete some of these tasks, you might need step-by-step instructions found in the VMware vSphere Upgrade Guide and the View Administrattion document.

For details about which versions of View are compatible with which versions of vCenter Server and ESXi, see the VMware Product Interoperability Matrix at http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.

Important:

To use the space-efficient disk format feature for linked-clone pools, you must upgrade vCenter Server, ESXi hosts, virtual machines, and the VMware Tools software in the virtual machines to VMware vSphere 5.1 or later.

To use the VMware® Virtual SAN™ feature, you must upgrade to vSphere 5.5 Update 1 or later.

Prerequisites

Procedure

  1. Upgrade ESXi hosts, cluster by cluster.

    For instructions, see the VMware vSphere Upgrade Guide. If you have many clusters, this step could take several maintenance windows to complete. Upgrading ESXi hosts might include the following tasks:

    1. Use VMware vSphere® vMotion® to move the virtual machines off of the ESXi host.
    2. Put the host into maintenance mode.
    3. Perform the upgrade.
    4. Use VMotion to move the virtual machines back onto the host.
    5. Perform post-upgrade tasks for ESXi hosts.

    Every host must be a member of a cluster, as mentioned in the prerequisites.

  2. If an upgraded host does not reconnect itself to vCenter Server, use vSphere Client to reconnect the host to vCenter Server.
  3. If you use View Composer, after all ESXi hosts are upgraded, on the vCenter Server host, restart the View Composer service.
  4. (Optional) : Upgrade VMware® Tools™ and the virtual machines on all parent virtual machines, virtual machine templates, and virtual machines that host View server components such as View Connection Server instances.
    1. Plan for down time, as described in the VMware vSphere Upgrade Guide.
    2. Update VMware Tools, and upgrade the virtual machine hardware for virtual machines that will be used as sources for remote desktops.

      To use the Windows 7 3D rendering feature, you must upgrade the virtual machine hardware to version 8 or later.

      To use the space-efficient disk format feature, you must upgrade the virtual machine hardware to version 9 or later. This feature pertains to linked-clone pools.

      If you use VMware vSphere® Update Manager™, you can update VMware Tools and then the virtual hardware version in the correct order for all the virtual machines in a particular folder. See the VMware vSphere Upgrade Guide.

  5. (Optional) : If you use full-clone desktops, on each virtual machine, upgrade VMware Tools and the virtual hardware for virtual machines that will be used as sources for remote desktops.

    To use the Windows 7 3D rendering feature, you must upgrade the virtual machine hardware to version 8 or later.

    If you use vSphere Update Manager, you can update VMware Tools and then the virtual hardware version in the correct order for all the virtual machines in a particular folder. See the VMware vSphere Upgrade Guide.
