Avaya Oceana® Disaster Recovery (DR) solutions include a primary datacenter location (DC1) and a DR datacenter location (DC2). DC2 is geographically separated across a suitably engineered layer 3 data network. For more detailed information about Avaya Oceana® Disaster Recovery, see Avaya Oceana® and Avaya Analytics™ Disaster Recovery.
There are two supported upgrade options for Avaya Oceana® DR solutions. Both upgrade options require an initial maintenance window to upgrade Avaya Aura® System Manager. This maintenance window is not service impacting, and you can schedule this maintenance window before upgrading the remaining solution components at a later time. For more information about Avaya Aura® System Manager upgrade, refer to the Avaya Aura® System Manager documentation, available on the Avaya Support website at https://support.avaya.com.
After upgrading Avaya Aura® System Manager, you must upgrade the remaining Avaya Oceana® components using one of the following options:
In a single maintenance window, upgrade all of the Avaya Oceana® components at both DC1 and DC2. This maintenance window is service impacting, Avaya Oceana® cannot be in production during this time.
In two separate maintenance windows, upgrade both datacenters at different times. Upgrade DC1 during the first scheduled window. This maintenance window is service impacting, Avaya Oceana® cannot be in production during this time. After the upgrade is complete and Avaya Oceana® is back in production, upgrade DC2. During the second scheduled maintenance window, you must re-enable data replication and full DR capabilities.
