+### Migrate the container
+To live migrate a container from one host to another the container is checkpointed on the source
+system of the migration, transferred to the destination system and then restored on the destination
+system. When transferring the checkpoint, it is possible to specify an output-file.
+
+On the source system:
+```console
+sudo podman container checkpoint <container_id> -e /tmp/checkpoint.tar.gz
+scp /tmp/checkpoint.tar.gz <destination_system>:/tmp
+```
+
+On the destination system:
+```console
+sudo podman container restore -i /tmp/checkpoint.tar.gz
+```
+
+After being restored, the container will answer requests again as it did before checkpointing. This
+time the container will continue to run on the destination system.
+```console
+curl http://<IP_address>:8080
+```
