This is the overview for the GetOldValue method overload.

 
Name 
Description 
 
Gets the value for a field as it was before the reception of this update. If the current update is the first one, then all old values are null.
If the "COMMAND logic" behaviour is enabled, then the value is meant as relative to the same key; as a consequence, on ADD commands all old values are null.
