# CNPG Cross-Region Migration
Migrate a single-instance CNPG PostgreSQL cluster between regions using the Standalone Replica Cluster pattern.
## When to use
- Migrating a database from Proxmox to Hetzner (or vice versa)
- Moving a database to region-appropriate storage
- No HA replicas exist — single-instance cluster only
## Procedure
Follow the runbook at `skills/cnpg_region_switch/RUNBOOK.md` step by step.
Key steps:
1. Create source cluster (if not existing)
2. Create target as streaming replica (`pg_basebackup` + `replica.enabled: true`)
3. Verify replication and data
4. Promote target (`spec.replica.enabled: false`)
5. Verify promoted target (writable, data intact, sequences correct)
6. Update application connection string
7. Delete source cluster
## Important constraints
- Both clusters must use the same PostgreSQL image version
- Promotion is irreversible (standalone replica pattern)
- Namespace must have quota for ≥6 services during migration (3 per cluster)
