Embodiments are directed to incrementally upgrading an entity-relationship system. In an embodiment, a computer system receives an indication that one instance including its own specified set of entities is to be upgraded to a second instance including a different specified set of entities. The computer system accesses the two instances to determine the differences between the entities of each instance. The computer system then discovers, based on the determined differences between the two instances, a set of actions that, when executed, change the entities of the first instance to the entities of the second instance. The set of actions is ordered such that processing order constraints are respected. The computer system then incrementally upgrades the entities of the first instance to the entities of the second instance by processing the determined set of actions in the appropriate, constraint-aware order.
