> Note: If you get a "Permission denied" error, your `/usr/local/bin` directory probably isn't writable and you'll need to install Compose as the superuser. Run `sudo -i`, then the two commands above, then `exit`.
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
Alternatively, if you're not worried about keeping them, you can remove them - Compose will just create new ones.
To uninstall Docker Compose if you installed using `curl`:
$ rm /usr/local/bin/docker-compose
To uninstall Docker Compose if you installed using `pip`:
$ pip uninstall docker-compose
> Note: If you get a "Permission denied" error using either of the above methods, you probably do not have the proper permissions to remove `docker-compose`. To force the removal, prepend `sudo` to either of the above commands and run again.
