Tectonic AWS clusters run in a static configuration. Use the latest Tectonic AWS documentation to create a new cluster and deploy your applications and services.
Tectonic bare-metal clusters should be reprovisioned using the latest Tectonic bare-metal documentation. If you've setup your infrastructure as described, skip to step 4. Use the Tectonic Installer application. Then set your servers to PXE on the next boot and reboot.
ipmitool -H node.example.com -U USER -P PASS chassis bootdev pxe
If you'd like to preserve and restore etcd data to the new cluster, see the etcd disaster recovery guide.
