Moving to Avaya Breeze® platform 3.9.0.3 from the releases 3.8.1, 3.8.1.1 and before requires a migration as mentioned in the chapter Method 1: Upgrading using OVA reinstallation of the Upgrading Avaya Breeze® platform documentation available on the Avaya Support website at https://support.avaya.com.
Deploy the Avaya Breeze® platform 3.9.0.3 OVA in vCenter to replace each node in the targeted cluster, using same IP, FQDN of current node.
ADDITIONAL INFORMATION:
Modify the memory, disk, and vCPU requirements for each component of Avaya Oceana® in addition to 2 GB RAM and 5 GB hard disk for each node. For information about the requirements, see Avaya Oceana® hardware requirements topic in the Deploying Avaya Oceana® documentation available on Avaya Support website at https://support.avaya.com.
Do not power on the virtual machines after deploying the OVA, until the previous virtual machines running the older versions of Avaya Breeze® platform are removed from their clusters and powered down. This is mandatory to avoid duplicate IP addresses running in your production network.
