+# iKhokha Migration SQL
+
+This folder contains SQL migration files to add iKhokha/provider metadata to the `payments` table and to migrate legacy `efts` records.
+
+Order to run:
+
+1. Backup your database (mysqldump or preferred tool).
+2. Apply `001_add_payment_columns.sql` on staging and verify schema changes.
+3. (Optional) Apply `002_migrate_efts_to_payments.sql` to copy legacy `efts` into `payments`.
+
+Commands (example using MySQL client):
+
+```bash
+mysql -u dbuser -p databasename < scripts/ikhokha_migrations/001_add_payment_columns.sql
+mysql -u dbuser -p databasename < scripts/ikhokha_migrations/002_migrate_efts_to_payments.sql
+```
+
+Notes:
+- Always test on staging before running in production.
+- `provider_response` is a JSON column used to store raw provider responses for audit.
+- If you prefer not to migrate `efts`, skip step 3 and keep legacy POP handling.
