You'll get paid those as usual, so if it takes 1 month or 2 or 3 or whatever it is / was then it will just stop after that.
You should have had an email indicating a switch over. I switched last year, around September or October.
It was much better for me as I was being paid in dollars and then losing out on converting to GBP, but now I just get paid directly in GBP. Of course you can't really compare the figures but I seem to do better out of it..
