Last Updated : Jun 10, 2026 |

Upgrade Avaya components and solution in the following sequence. If any of the Avaya components are not part of your solution, you can skip that particular component and move to the next component.

If you choose the Optional Upgrade Sequence feature, you can upgrade the core Communication Manager before you upgrade your Survivable Remote Servers (LSP). In the following Optional Upgrade Sequence, you can skip steps 12 to 14. Note that if you skip the order of sequence, skip all the optional steps.

Disclaimer on Upgrade Sequence Flexibility

While Avaya recommends following the documented upgrade sequence to maintain solution stability and validated integration, the sequence allows flexibility in specific scenarios. Avaya supports component versions that may be ahead or behind others in the upgrade path, provided they are documented in the Product Compatibility Matrix published on the Avaya Support site. Customers may upgrade individual components out of sequence where such configurations are certified to be interoperable.

Refer to the Product Compatibility Matrix before performing any upgrades out of sequence.

For the latest and most accurate compatibility information, go to http://support.avaya.com/CompatibilityMatrix/Index.aspx.

    All applications supported by System Manager do not follow the general Avaya Aura® Release numbering schema. Therefore, for application versions System Manager supports, see Avaya Aura® Release Notes on the Avaya Support website.
