5. Remove the previous Rancher Server container.
If you only stop the previous Rancher Server container (and don't remove it), the container may restart after the next server reboot.
6. Log into Rancher. Confirm that the upgrade succeeded by checking the version displayed in the bottom-left corner of the browser window.
**Result:** Rancher server is upgraded to the latest version.
