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.
Procedure
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.
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.
