What's Changed
Warning
To migrate, run make migrate-clusters-terraform followed by make apply to update your configuration and create a new build managed group. Once the new build nodes appear in Nomad, drain the old build nodes, including system jobs. After all old nodes are fully drained, you can run make plan as usual; this will remove the old build instance group.
