IMPORTANT: If you are downgrading to a previous version of the HP EFS WAN Accelerator
software, you must downgrade to a version of the software that has previously run on your
machine. For example, you cannot upgrade from v1.2.3 to v2.0 or v2.1 and downgrade to
v1.2.8—you must downgrade to v1.2.3. and then upgrade to v1.2.8. If you do not follow this
step, your configuration will be discarded in an unrecoverable way. (Work-around: either go
back to a previously installed revision, or save the text results of a show running-configuration
command before downgrading in a machine other than the HP EFS WAN Accelerator, and apply
it after the downgrade.)
