With the dual boot feature, you can switch between two installed versions of Spirent
TestCenter using the command line interface. You can identify the current version and
standby version using the appropriate commands described in this section.
For SPT-C1/SPT-C2 appliances, the feature applies to Spirent TestCenter releases 4.94
and later. When you initially upgrade to release 4.94 or later, both installed versions will
be 4.94 or later. Subsequent upgrades to releases later than 4.94 will result in two separate
partitions, containing the current version and the standby version, respectively.
Notes: • Downgrading to a Spirent TestCenter version below 4.94 removes this
feature.
• If you are using Spirent TestCenter version 4.53 or earlier, and you want to
upgrade to version 4.94, go to the Customer Service Center (CSC)
Knowledge Base, and follow the instructions in FAQ11021.
• Downgrading to 4.81 or below is a two-step process (if you are at 4.94 or
above). First downgrade to 4.81 and then to the version you intend to use.
