os: Mac osx mojava 10.14.6
docker: docker desktop community 220.127.116.11
When I use checkupdate and upgrade my docker desktop to version 18.104.22.168. I found that all my containers & images are gone. And I did a close look about this. I found that the disk is set to $HOME/Library/Containers/com.docker.docker/Data/vms/0/Docker.raw
And the disk of vms is Docker.qcow2 in the previous version.
My question is what should I do to migration from qcow2 to raw???
Is the expected behavior after upgrade???
