Abstract: A system is upgraded by rolling upgrade with dynamic batch sizes in multiple iterations. The system includes multiple hosts that host multiple resources. The rolling upgrade calculates a number of hosts to upgrade and a number of resources to upgrade for each iteration. The calculation subtracts a reserved number of hosts from a capacity of the system to account for potential failover and potential resource scaling operations during the iteration. Based on the calculated number of hosts to upgrade, it is determined whether the system has a capacity for upgrade. If the capacity exists, the calculated number of hosts to upgrade and the calculated number of resources to upgrade are upgraded, while accepting resource scaling requests during the iteration.
