If you want to migrate an Avaya UC or CC application that is currently licensed under a perpetual license to a subscription license, ensure that the perpetually-licensed (on-premise) application is of either the minimum version supported by Avaya OneCloud™ Subscription or of a later version.
If the perpetually-licensed (on-premise) application is of an earlier version than the minimum supported version by
Avaya OneCloud™ Subscription, then before adding the application to the
Avaya OneCloud™ Subscription system, upgrade the application to at least the minimum supported version. For more information, see
Migrating applications from perpetual licenses to subscription license.
