In the Management Console, choose Administration > Maintenance: Licenses. Click Stop to stop the acceleration service, and log out of SteelHead-v. Right-click the name of the virtual machine that you want to upgrade, select Power, and select Power Off.

In the vSphere Client, right-click the name of the virtual machine that you want to upgrade and select Edit Settings. Check the memory, CPU, and hard disk settings. Change any setting necessary to accommodate the model upgrade. For more information about changing memory, CPU, and hard disk settings, see Downgrade limitations.

Right-click SteelHead-v, select Power, and select Power On. Log in to SteelHead-v and display the Management Console.

Choose Administration > Maintenance: Licenses to display the Licenses page. The bottom of the screen lists the available appliance specifications. The current specification appears in bold. The hardware specification description includes the potential bandwidth and connection counts. Appliance specifications that will be available after the license or required virtual hardware have been installed are included in the list but are grayed out.

Select the hardware specification that you want to activate. If a hardware specification requires a reboot after activation, you see the message “activation reboots appliance.” Click Apply.

SteelHead-v reboots and the acceleration service restarts. When the upgrade is complete, the new model number appears on the SteelHead-v banner in the upper-right corner of the screen.
