Enabling And Securing Upgrades - Avaya Scopia XT Series Deployment Manual

Upgrading to a major version requires a new license key. The first and second digits in the version
number indicate the major version number. For example, in version 3.1.0.005, the major version
number is "3.1".
You can always downgrade the system to a previous version. Beginning with this release, the XT
Series only accepts verified signed software packages. In 9.0 recovery mode or higher, you
cannot downgrade to 8.3.x or use an unsigned package. In 9.0 standard mode, you need to
disable Verify Signature to downgrade from this release using an unsigned package. Contact
your local customer service representative for more information.

About this task
You can remotely upgrade your Avaya Scopia
Management or from a remote Windows computer running the XT Series upgrade program. XT
Series software packages are signed by an Avaya Certificate Root Authority. Beginning with this
release, the XT Series only accepts verified signed software packages. To downgrade the XT
Series to a previous version, you must manually disable the verification.
Important:
In recovery mode, you cannot upgrade an XT Series using an unsigned package. You must
use a signed package to upgrade the XT Series in recovery mode, then disable the
verification and use the unsigned package in normal mode.
You can also limit the range of IP addresses allowed to upgrade the unit remotely.
