We have 3 license servers for ESRI products.

  1. Server 1: 10.1 License Server
  2. Server 2: 10.0 License Server
  3. Server 3: 9.3 License Server

We are in the middle of a massive server migration/merge and would like to combine our license servers into one and store it on a single centrally-located machine. But we have some specific applications that require 9.3, a few that require 10.0, and our more common use-cases are migrating to 10.1 so we can't just upgrade the licenses. But keeping them on different servers won't work because we are losing some of our servers due to a reshuffle.

So, with 9.3 Concurrent use licenses being utilized, can we store those alongside 10.0 and 10.1 licenses on the same server without losing them?

Your 10.1 license server can host cocurrent use licenses for all 10.x and 9.x products. We have a 10.1 license manager in production, our client environment is mix of 10 and 10.1 products.
