# HTTPRoute cutover runbook
Current production domains are owned by `ircs-system` routes:
- `huawai.sophia.fr.eu.org` -> `ircs-system/huawai-svc:80`
- `ircs.sophia.fr.eu.org` -> `ircs-system/ircs-frontend-svc:80`
V3 production routes are declared under `ircs-prod/edge-cutover`:
- `huawai.sophia.fr.eu.org` -> `ircs-prod/ircs-frontend-gateway:80`
- `ircs.sophia.fr.eu.org` -> `ircs-prod/ircs-frontend-gateway:8080`
Cutover order:
1. Confirm `ircs-prod` pods are Ready.
2. Confirm cluster-internal portal/admin smoke is healthy.
3. Disable automated sync on old `argocd/ircs-app` so it does not recreate old routes.
4. Apply edge routes and delete old `ircs-system` business routes.
5. Verify Envoy Gateway accepts the new routes.
6. Verify external domains through the NLB/Cloudflare path.
Use `scripts/cutover-httproute.ps1 -Execute` from this repo root when ready.
