Did you receive some kind of update saying your file was transferred to NDVO?
In my case, i got the update from my MP's office. There is no indication in my cic account or ECAS saying the file was transferred from Mississauga to New Delhi.
I got a letter in mycic about that transfer.
But you should not worry about if you did not receive that letter, they miss things sometimes.
As you got pre-arrival and DM2 same day, that means a positive outcome.
You may receive PPR within next week.
