Software Upgrade & Downgrade
This section explains how to upgrade or downgrade XT Series software.

Signed Software Packages

Since release 9.0, XT Series software packages are signed by an Avaya Certificate Root Authority
recognized by the XT Series.
Only verified signed software packages will be accepted by XT Series once upgraded to this
release.
A software package will be installed only if XT verifies that:
•
The software package is signed by Avaya IT Root Authority and produced by an authorized
build server.
•
The software package content is not tampered or changed in any way.
For this reason, the XT Series upgraded to 9.0 releases will no longer accept by default software
packages which have not been signed.
This means that to downgrade XT Series to a previous version you must manually disable the
verification of the downloaded package signature. Browse to:

unsigned package by setting "Verify Signature" to No.
** XT7000 does not accept the package due to memory capacity.

Important
•
The Verify Signature option does not apply to recovery mode. It is not possible to
force an XT version 9.0 or higher to accept an unsigned package when in recovery
mode. See Known Issues, "Software Upgrade & Downgrade" section and the table
below.
Important
•
The signed package version cannot be uploaded directly on an XT running a version
8.3.x or earlier by USB or XT Web interface or AT interface or iView. You need to
use a special unsigned package in this case. Ask Customer support to receive an
unsigned package.
