IP Office release 10 and higher supports only the Product Licensing and Delivery System (PLDS) to manage license files. If you are upgrading from a previous release, you must migrate all of your pre-R10 licenses (ADI, PLDS, mix of ADI/PLDS, virtual) to R10 PLDS licenses. The license migration tool extracts all the licensing information from an IP Office system and saves it to a file. This file can then be used prepare a software upgrade quote in the Avaya One Source Configurator in order to obtain the required new PLDS R10 licenses.
For Server Edition deployments, the License Migration tool collects licensing information from every node in the solution.
For a step by step procedure, see Migrating Licenses to PLDS.
