Edit a Custom Domain

You can change only the Certificate of a Custom Domain. The Domain name stays the same. The change applies at once, and you don't need to update DNS because the Load Balancer IP does not change.

To replace an expiring Certificate for every Custom Domain that uses it, renew the Certificate instead of editing each Custom Domain.
