Avaya issued an End of Support notice in Jun-21-21 in accordance the Avaya Product Lifecycle Policy.  Avaya will no longer make commercially available or support SAL Gateway 3.x, Policy Manager 3.x, and SLA Mon Server 3.x. Note that SAL Gateway 3.x and SLA Mon Server 3.x are packaged together as Avaya Diagnostic Server 3.x. Policy Manager 3.x is a separate software application used with SAL Gateway 3.x. End of support date for 3.x was Dec-31-22. 

To deliver new features and latest security and technology updates, Avaya is introducing Avaya Diagnostic Server 4.0 (which includes SAL Gateway and SLA Mon Server packaged together) and Policy Manager 4.0.

With the announcement of End of Support for SAL Gateway 3.x, Policy Manager 3.x, SLA Mon Server 3.x., Diagnostic Server 3.x, Policy Manager 3.x, Avaya will not provide any new development for the product. This means:

  • No security updates (corrective fixes for security related issues typically identified at the operating system or kernel level) will be made available. 
  • No new bug fixes (corrections for software defects delivered via patch, service pack, security update or feature pack and corrections to hardware defects as needed) will be made available.
  • No new or modified features or capabilities will be made available. 
  • Risk of incompatibility and impact in functionality with new releases of Aura and other products in the future.

For these reasons, NWN Carousel is strongly recommending that customers upgrade to the new release so that they are not subject to increased security vulnerabilities and risk. 

Alarming and remote access capabilities through SAL Gateway will continue to function as they do today but if there are any issues found that require a patch or application update an upgrade will be required.

Yes. We’re happy to consult with you on the various options.  This work is not service affecting.  During the migration, the system cannot be accessed remotely, and it cannot send alarms proactively. After you complete the implementation, we can schedule testing to ensure the migration is complete.

Yes, you do.  This migration provides new features and latest security and technology updates, Avaya is introducing Avaya Diagnostic Server 4.0 (which includes SAL Gateway and SLA Mon Server packaged together) and Policy Manager 4.0.

No, migration of the SAL does not impact the service or operation of your Avaya platform.  During the migration, when the current SAL is removed and moving to the new release, neither NWN Carousel or Avaya will be able to remotely access your system, nor will the system proactively alert Avaya or NWN Carousel.  The work can certainly be done within business hours, and we suggest performing within business hours, so testing can be done more readily.

Avaya is keenly focused on providing the highest level of security for its customers. Diagnostic Server 4.0 is the most secure gateway yet.
