Upgrading SteelHead CX, EX, and SteelFusion Core Appliances
This chapter describes how to upgrade SteelHead CX, EX, and SteelFusion Core appliances. It includes the following sections:
Overview
A model upgrade enables you to add a license to an existing CX, EX, or SteelFusion appliance to increase the capacity and the model number of the appliance within its platform family.
You can install licenses using the Riverbed command-line interface (CLI) or the SteelHead Management Console. Model upgrades always preserve the configuration of the appliance.
In some cases, model upgrades require the installation of additional disk drives and memory modules. Upgrades that require the installation of additional hardware don’t preserve the data store.
Model upgrades and platform requirements

Notes:
• The CX7070 and CX7055 appliances don’t provide a model upgrade through a license. To upgrade these appliances, you need to exchange the appliance. During this upgrade, there is no data store migration. For more information about this upgrade, contact the Riverbed SalesOps team.
• You can’t upgrade an EX1260 (2 TB) to an EX1260 (4 TB).
• Once you perform a VH upgrade for a SteelHead EX, you can’t downgrade to a software version earlier than 3.5.
• Newer EX 1160 and 1260 appliances—those with SKUs that end with a 5—require a minimum software version of 2.5.3.
• The upgrade process from a G specification to a VH specification is a two-step process: first, upgrade from a G to a L/M/H specification and then upgrade from the L/M/H specification to the VH specification.
