The steps to follow are:

1. Stop the MySQL replication in all the slaves and master zone. The MySQL replication is no longer needed.
2. Upgrade the **master** zone to 5.4 version
3. Upgrade the **slaves** zones to 5.4 version
2. Upgrade the **master** zone to the latest version
3. Upgrade the **slaves** zones to the latest version
4. Replicate the state of the shared tables from the master zone into each slave zone.

During steps 1 and 2 the slave OpenNebula's can be running, and users can keep accessing them if each zone has a local Sunstone instance. However all the shared database tables (users, groups, ACL...) will not be updated in the slaves zones till step 3 is completed.
