```bash
# ensure the project has no cluster again
# ensure the network is hibernated status
kg --context=infra cluster,network -n prod-1
# dry-run=true
./migrate empty-network --key prod-1/aws-us-west-2 --aws-ctx-reg infra --eks-ctx-reg infra --gardener-ctx-reg ^garden$ --gardener-ns=garden-prod --dry-run=true
# ensure delete AWS resources is correct, then set dry-run = false
./migrate empty-network --key prod-1/aws-us-west-2 --aws-ctx-reg infra --eks-ctx-reg infra --gardener-ctx-reg ^garden$ --gardener-ns=garden-prod --dry-run=false
```
- Impact: if the user create cluster during the period, we need to delete it manually
- Recovery operation: `None`
- Time window:
