After a VirtuCache driver update – the prior configuration is automatically applied
If you upgrade VirtuCache by uninstalling the earlier vib and installing a new vib, you don’t need to move VMs or Datastores to uncached mode before you start the upgrade process. Simply put host in maintenance mode. Uninstall the old vib . Install new vib. Caching at the host level is now automatically turned on using the new caching driver vib, and the last known configuration is applied automatically. This happens because we keep the caching configuration file in a Datastore , so we simply import the last known config from the Datastore and apply the same caching policies you had before, to all the VMs and Datastores on that host.
