Mysql Cluster 7.5 to 7.6 upgrade

I tried to upgrade my 7.5 cluster to 7.6 yesterday and couldn't get it to work, forcing a rollback. Are there any simple upgrade instructions available?

In my case, none of the components could communicate with each other. I upgrade one manager (I have two) and nothing connected to it except itself. Then I tried to upgrade one data node and it couldn't connect to the manager. There is probably something wrong with my configuration file, but I have no idea what it might be. If anyone has some simple upgrade instructions, I'd appreciate your sharing them.
