You posted this question from the other thread. The answer is complicated.
If you're switching specialties, then the new PD decides how much of your old credit can get transferred.
If you're staying in the same specialty, then (in general) your old PD decides how much credit you get. But I expect the new PD might be able to override that.
If you're completing a prelim year for some advanced specialty, then the old PD will ceritfy that.
It's really petty of them to make an issue of this. You should print out all of your evaluations now. They might cut off your access, or edit them. Het hard copies of everything, or save digital copies to a cloud drive you have access to. If they were to take some employment action, you can find all of your email and other computer access cut off instantly.
