PFItemEnableVersionMergeToResolveSaveConflicts Property

If an object is saved with an older version than the last persisted (in database), the system will try to merge the versions values (if no conflicts between values) and will then save the merged item to database. Note : this setting is NOT persisted and will affect this object instance only.

public override bool EnableVersionMergeToResolveSaveConflicts { get; }
