### Upgrading
If you're coming from Compose 1.2 or earlier, you'll need to remove or migrate your existing containers after upgrading Compose. This is because, as of version 1.3, Compose uses Docker labels to keep track of containers, and so they need to be recreated with labels added.
If Compose detects containers that were created without labels, it will refuse to run so that you don't end up with two sets of them. If you want to keep using your existing containers (for example, because they have data volumes you want to preserve) you can migrate them with the following command:
docker-compose migrate-to-labels

docker rm -f myapp_web_1 myapp_db_1 ...
