How do I upgrade my network?
Since you cannot link 3.2.x to 5.x you have two options: -OR-
 * Upgrade all servers at the same time, from 3.2.x to 5.x, in 1 big move. That is: kill all 3.2.x servers, then start all 5.x servers. Of course, best to first test your setup on a small test network.
 * Do a two-stage upgrade:
 * 1) Upgrade all your servers gradually (one by one) from 3.2.x to 4.x
 * 2) After all that is done. You can now upgrade gradually (one by one) from 4.x to 5.x.
