Prerequisites for an upgrade or update to AE Services

Last Updated : Jun 10, 2026 |

From Release 10.1 onwards, the default Communication Manager identity certificate signed by the SIP Product Certificate Authority is not accepted due to security hardening. So, install a third-party CA certificate on AE Services and an identity certificate on Communication Manager.

The public key of the CA and identity certificates should not be less than 2048 bits. You must install the certificates on AE Services and Communication Manager before upgrading to AE Services Release 10.2.

Before you start the upgrade, make sure you have the following items:

  • Administrative workstation.

  • (Optional) A program to back up the AE Services server drive: Use a program that enables you to copy the entire content of the AE Services server drive. Avaya recommends creating a backup of the AE Services server drive before upgrading the AE Services software.

  • AE Services Release 10.2.x software that includes pre-upgrade patch files and features or service pack files.

    To upgrade AE Services from Release 8.0.x and later to Release 10.2.x, use the following options:

    • You can download the ISO file of the Application Enablement Services software for Release 10.2 and create an installation DVD.

    • You can mount the ISO file on the file system and then use the file to install the server.

  • The Linux® Operating System RHEL 8.4 or RHEL 8.10 (64 Bit) has received all security updates. For more information, see the Hardware Requirements section.

  • AE Services Release 10.2.x license file: A new license is required to upgrade AE Services from an earlier major release. For example, in AE Services 8.1.x., uninstall the license file if you are upgrading from a major release to another release. To obtain a license file, see Obtaining the AE Services license file.

    Note:

    Release 7.1.3.x version is supported only during the transient period while upgrading the Avaya Aura® solution.

    Important:

    Ensure you request the license file a day before you upgrade.

  • (Optional) Release Notes: To obtain the release notes, visit the Avaya Support site at https://support.avaya.com.
