[My query is about PNR 8705194458 for train 14312 ALA HAZRAT EXP]
if you have checked the auto-upgradation option while booking then you will be provided berth if there will be any vacant berths available in higher class. but it can not be upgraded if you have not checked that option while booking. as such your ticket status is confirmed. you will be provided berth in the sleeper class after chart preparation.
This is called down grade not up grade
