ABSTRACT:
Aspects of the subject matter described herein relate to system state changes. In aspects, a state change monitor detects a state change, determines whether the state change is within a set of state changes that are monitored, and, if so, logs data regarding the state change. The data and any other data needed to rollback the state change is exported to other nodes. The other nodes may store the data for rollback or migration purposes and/or adjust their operation so that they may operate correctly in view of the state change.
