--- Brief online upgrade procedure --
Prerequisite: You have a running cluster with NoOfReplicas > 1
1) take backup, only to be used if something goes wrong.
2) restart each ndb_mgmd, one at a time (with new version :-))
3) restart each ndbd "--initial", one at a time
The starting node will then resync with rest of cluster.
4) restart each mysqld
Result: new version running, no downtime.
