You can use System Manager Solution Deployment Manager, the centralized upgrade solution, to upgrade Application Enablement Services.
With Solution Deployment Manager, you can upgrade Application Enablement Services from Release 7.1.3.x, 8.0.x, 8.1.x, or 10.1.x to Release 10.2.x OVA.
Note:
7.1.3.x version is only supported in the transient period when upgrading the Avaya Aura® solution.
Before upgrading Application Enablement Services to Release 10.2, Avaya recommends that the older Application Enablement Services Release version must be on the latest version of its releases. The latest version for Release 7.1.x, 8.0.x, 8.1.x, and 10.1.x are Release 7.1.3.8, 8.0.1.2, 8.1.3.8, and 10.1.3.1 respectively.
If you are upgrading to Release 10.1 or later, the certificate hostname validation is enabled automatically for an external WebLM server and for all Communication Manager connections.
After the Enable Certificate Hostname Validation field is enabled, AE Services verifies the certificate identity in the Subject Common Name (CN) or Subject Alternate Name (SAN) field of the certificate for the external WebLM server and Communication Manager connections.
If the certificate identity matches with the FQDN/IP address of the WebLM server or with the Communication Manager , then the connection with the external WebLM server and Communication Manager is established, otherwise the connection is dropped.
The server identity certificate must have the following values to establish a secure connection with the WebLM server:
Key Usage: Digital Signature, Key encipherment
Extended Key Usage: id-kp-clientAuth, id-kp-serverAuth
Note:
Extended Key Usage is an optional field, it must have the mentioned values only if it is present in the certificate configuration.
The connection will be dropped if the certificate does not meet the above criteria.
If the connection is dropped after the upgrade, do one of the following to re-establish the connection:
Disable Enable Certificate Hostname Validation field. For more information, see Administering Avaya Aura® Application Enablement Services.
Add IP address in Subject Alternate Name field of the identity certificate of Communication Manager or external WebLM server. For more information, see Communication Manager or System Manager and WebLM documentation.
Use a resolvable FQDN present in the Subject Alternate Name field of the WebLM server or Communication Manager identity certificate. If DNS is not available, add the FQDN to IP address mapping for the host files on AE Services server.

Note:
To upgrade Application Enablement Services by using Solution Deployment Manager, you must have System Manager.
