+### Migrate unsupported user notification rules
+
 It's possible to specify a default contact method type for user notification rules that cannot be migrated as-is by
 changing the `ONCALL_DEFAULT_CONTACT_METHOD` env variable.
 Options are: `email`, `sms`, `phone_call`, `slack`, `telegram`, `mobile_app` (default is `email`).
 
+### Migrate unsupported integration types
+
+It's possible to migrate unsupported integration types to [Grafana OnCall incoming webhooks](https://grafana.com/docs/oncall/latest/integrations/available-integrations/configure-webhook/).
+by changing UNSUPPORTED_INTEGRATION_TO_WEBHOOKS env variable:
+
+```shell
+docker run --rm \
+-e PAGERDUTY_API_TOKEN="<PAGERDUTY_API_TOKEN>" \
+-e ONCALL_API_URL="<ONCALL_API_URL>" \
+-e ONCALL_API_TOKEN="<ONCALL_API_TOKEN>" \
+-e ONCALL_DEFAULT_CONTACT_METHOD="sms" \
+-e MODE="migrate" \
+-e UNSUPPORTED_INTEGRATION_TO_WEBHOOKS="true" \
+pd-oncall-migrator
+```
+
+Consider modifying [alert templates](https://grafana.com/docs/oncall/latest/alert-behavior/alert-templates/) of the created
+webhook integrations to adjust them for incoming payloads.
+
 ### After migration
 
 - Connect integrations (press the "How to connect" button on the integration page)
