Upgrading Flash Accel Host Agents
You can use the Flash Accel Management Console to upgrade Host 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 host, or use a bulk upgrade to upgrade agents on multiple hosts.
Before you begin 
ESXi hosts must be in maintenance mode before you can upgrade Flash Accel Host Agents. All running virtual machines must be migrated to another host (either manually or automatically by DRS) or shut down. You can then right-click the host using the vSphere Client and select Enter Maintenance Mode.
Steps 
1.
From the FMC Host Inventory page, select each host on which you want to upgrade Flash Accel software and click Host Agent Upgrade in the Bulk Actions area of the FMC.
The host upgrade dialog box opens.
2.
Click Upgrade.
Result 
The Flash Accel Host Agent is upgraded on the host.
After you finish 
You must take ESXi hosts out of maintenance mode before you can resume caching. In the vSphere Client, right-click the ESXi host and select Exit Maintenance Mode. You can then power on the VMs on the host, or if you had moved them to another host, move the VMs back over to the host.
