Account Number Migration
One-time migration to assign RC-00001, RC-00002 format to existing customers
Migration Instructions
This migration will:
- Assign sequential account numbers (RC-00001, RC-00002, etc.)
- Process customers in chronological order (oldest first)
- Skip customers that already have proper account numbers
- Update customer records automatically
⚠️ Important: Run this migration only once. It's safe to re-run if needed (will skip already migrated customers).
