Recently our pega7.3 application got upgraded to pega8.3. It is based on pega cloud and postgres DB. Post upgrade our application is behaving abruptly. The uniqueID (instance of Data-UniqueID) is getting increasing abruptly. That means, if case id created with CC-100, the next case is creating as CC-1101. The pyLastReservedID is getting increased abruptly. Not sure, from where it is getting increased ? The issue is specifically happening after upgrade.
