Upgrading vSphere Components Separately in an Omnissa Horizon 8 Environment

If you upgrade vSphere components separately from Horizon 8 components, you must back up some Horizon 8 data and reinstall some Horizon 8 software.

Instead of performing an integrated upgrade of Horizon 8 and vSphere components, you can choose to first upgrade all Horizon 8 components and then upgrade vSphere components, or the reverse. You might also upgrade only vSphere components when a new version or update of vSphere is released.

When you upgrade vSphere components separately from Horizon 8 components, you must perform the following additional tasks:

1. Before you upgrade vCenter Server, back up the vCenter Server database.

2. Before you upgrade vCenter Server, back up the Horizon Directory database from an Omnissa Horizon Connection Server instance by using the vdmexport.exe utility.

   For instructions, see the Horizon 8 Administration document. If you have multiple instances of Horizon Connection Server in a replicated group, you need to export the data from only one instance.
