When you get in process on applicant's ecas it means it's been sent to the vo.
when you get aor2 it means they are working on the file.
so yes, there are 2 separate things
we got an email regarding the transfer once ecas went to in procress. "we sent your app to london vo for further processing etc etc". we have not heard anything since we got aor2 (the additional line in ecas, which was 5m ago).
