Upgrading Flash Accel Guest OS Agents
You can use the Flash Accel Management Console to upgrade Guest OS Agents with minimal disruption to your system. As long as you upgrade VMs before you upgrade hosts, you can resume caching with minimal rewarming. You can upgrade the agent on a single VM, or use a bulk upgrade to upgrade agents on multiple VMs.
Before you begin 
It is a good idea to take a snapshot of your VMs before you upgrade the software, in case you need to revert to an earlier version.
Note: The virtual machine is shut down or restarted when the upgrade completes. You need to be sure this is an acceptable time to take the virtual machine offline.
Steps 
1.
From the FMC VM Inventory page, select each VM on which you want to upgrade Flash Accel software and click VM Agent Upgrade in the Bulk Actions area of the FMC.
The virtual machine upgrade dialog box opens.
2.
Click Upgrade.
Select the Reboot check box if you want to restart VMs automatically after upgrade.
Result 
The Flash Accel Guest OS Agent is upgraded on the VM. If you selected the Reboot check box, the VM is restarted. Otherwise, it is shut down. Restart the VM to resume caching.
Note: Flash Accel sets the disk.enableUUID flag to TRUE on the VM if necessary.
