If I am understanding this correctly, from Groovy to Edge Device Migration List - Announcements - SmartThings Community, the migration of listed devices is continuing. I am still waiting for about half of my devices to migrate.
Below is a quote from that web page…
Note: Your device type may be on the list and still not have migrated. That does not mean your device will not be migrated, it may just be done at a later time. We will have an announcement posted later addressing devices that fall into this category.
