To answer your question, the Bridges for UNIX v1.1 licenses would need to be upgraded to v2.0 licenses, which would also need to be upgraded to v2.1 licenses. However, a v2.0 license works for 2.0.0, 2.0.1, 2.0.2, and 2.0.3. A v2.1 license will work with any forthcoming v2.1.x releases.
Hope this helps,
Troy
