Avaya will likely require all new licenses (system, user, trunk) for those locations. Server licensing is very expensive and requires IPOSS for at least one year - if you are going the server route, you will need a physical or virtual server - and thus Avaya will require two server licenses for each location : one for the server and one for the V2. And IPOSS for both. Unless you can just get by with the V2 as Essential or Server without V2. You may be able to get Avaya to allow the licenses to be transferred, but you will have to provide legal documentation and “official” documentation that shows that those entities were sold. And Avaya has various secret requirements for when they will allow this and when they won’t which they don’t publish. But you should certainly try. If the requirements don’t call for SE, you should consider Essential or Preferred. Preferred is a bit tricky when it comes to pricing because although it’s less expensive than SE, it requires you to use the V2, and therefore double IPOSS! Contact me privately if you’d like further details regarding Avaya’s review. In general, they will only do these types of transactions when the company or a division of the company, and all of its employees and assets are sold or acquired or combined or spun off. They will not do it when it’s simply an asset sale e.g. you purchased a bunch of equipment. Also, please keep us posted on what you ended up doing both in terms of the technology and a via licensing/policies.
