https://subeta.net/legacy_shops_migrate.php If you go here you should be able to move everything.

I've taken a look; your legacy shops should now show up in the dropdown now on the Migrate page. Could you please check again, and give it a try?

However, one small note - we just started having an issue with the sidebar event when it completes. It is supposed to notify you when the migration is finished, but at the moment the event is not working and we're still working on fixing that. The rest of the migration works fine (I just tested it)

You can notice when it finishes because you'll suddenly have 4.9m sP more on-hand, and the shop also gets deleted when the migration completes (so it won't be under the commerce tab anymore in the navbar). Apologies for the inconvenience!
