The "instanceIds" parameter contains all the ids of instances that are allowed to perform synchronizing operations
with the current parent server. Empty value means that all children are allowed to synchronize
OpenMRS Sync 2.0 synchronization also allows to solve conflicts that may occur during multiple changes on many instances.
Depending on the setting of "sync2.mergeBehaviour" global property, conflicts can be solved in two ways:
- When set to: "sync2.newIsTheBestMergeBehaviour", newer changes are automatically integrated
- When set to: ""sync2.restrictConflictMergeBehaviour"
