Great prediction Sir. I knew this was gonna confirm but did not expect an upgradation. The data from the official website shows that there was only a single upgradation yesterday for 12245 and that was from 2AC-1AC. Perhaps the cancellation of one passenger facilitated in the process of smooth upgradation.
I shall be going to HWH tomorrow to check whether there has been any other upgradation apart from this one.
PS:- Coincidentally there is a recent discussion going on in IRFCA regarding Auto upgradation! :)`
