The AS2 certificate used currently is approaching expiration.

1. Verify which AS2 certificate is currently active in the managed gateway and confirm whether the referenced expiring certificate is actually in use.
2. If the expiring certificate is in use, plan a maintenance window and notify applicable partners that an AS2 certificate update will occur.
3. Update the AS2 certificate in the managed gateway by following the steps in the referenced documentation.
4. After updating, validate AS2 message exchange end-to-end (send and receive) and confirm successful MDN processing.
5. Monitor for any post-change connectivity issues and roll back only if required by your change procedure.
