+# Migrate Inter-Hub data and cut over production
+
+Move production framework responsibility from Haskell Inter-Hub to Core Hub only after compatibility evidence exists.
+
+## Design Migration Path
+
+```task
+id: CORE-WP-0005-T01
+status: wait
+priority: high
+state_hub_task_id: "01909b75-2229-41e2-a61a-c4c9ef84c232"
+```
+
+Define export/import flow, migration batches, row-count checks, relationship checks, and rollback. Waits on CORE-WP-0002 and CORE-WP-0003.
+
+## Run Staging Import
+
+```task
+id: CORE-WP-0005-T02
+status: wait
+priority: high
+state_hub_task_id: "e0ea0928-a3ea-4ece-bbb7-ee08f8a3279b"
+```
+
+Import production-safe or full approved Inter-Hub data into Core Hub staging. Record counts and discrepancies.
+
+## Dual-Run Smokes
+
+```task
+id: CORE-WP-0005-T03
+status: wait
+priority: high
+state_hub_task_id: "9166afe8-27ef-4345-a7b1-c33f15c90673"
+```
+
+Run public and protected smokes against both Inter-Hub and Core Hub. Record compatibility deltas.
+
+## Production Cutover
+
+```task
+id: CORE-WP-0005-T04
+status: wait
+priority: high
+state_hub_task_id: "fa68858a-b18e-4f09-a477-6b11e54099d4"
+```
+
+With operator approval, switch production traffic such as `hub.coulomb.social` to Core Hub. Keep rollback available until stabilization passes.
