I would also like to share my timeline here. My COPR expired in March 2020. My account was silent for a long time, didn't even get a single ghost update. Sent multiple queries to IRCC via the web form. Finally in March 2021 I got a request for re-medical and self declaration for background check-form IMM5669E. I got the "do you still want to migrate" mail after I got my re-medical request. Did my medical test on March 29th and on April 14 I got the passport request. Finally in July I got my new COPR and passport stamped with new Visa.
