Software Upgrade & Downgrade
This section explains how to upgrade or downgrade XT Series software.
This release introduces also relevant improves in software upgrade security, using signed software
packages.

Signed Software Packages

Since this release, 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:
1) The software package is signed by Avaya IT Root Authority and produced by an authorized
build server.
2) The software package content is not tampered or changed in any way.
For this reason, the XT Series upgraded to this release 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 have to manually disable the
verification of the downloaded package signature. Browse to:
