Steelhead Appliance Installation and Configuration Guide
Overview of the Steelhead EX
Upgrading to Version 2.1
If you mix software versions in your network, the releases might support different optimization features
and you cannot take full advantage of the features that are not part of the older software versions.
Since the Steelhead EX software image includes the ESXi software, the image upgrade might upgrade the
ESXi version used by VSP. If you have not changed the ESXi version outside of Steelhead EX, the ESXi
version will be updated to match the new install image, if necessary. If you have modified the ESXi version
for VSP independently of the Steelhead EX image, the software upgrade does one of the following:
If the existing version of ESXi is older than the version in the image file, the image upgrade updates the
ESXi version. The configuration will not be affected.
If the existing version of ESXi is newer than the version in the image file, the image upgrade does not
change ESXi. The configuration will not be affected.
If the version cannot be determined, ESXi will be upgraded to the version in the image file. The ESXi
configuration might be lost. As a best practice, back up your existing configuration before proceeding.
Note:
It is not supported to modify the ESXi version independently of the Steelhead EX image. You can verify the
version number and the support status of the running ESXi installation on the Support page of the Management
Console.
