A hostname or route change can break bookmarks and external links even when the new application is otherwise healthy.
Inventory hostnames and important paths, preserve redirects, validate TLS and canonical URLs, and test common saved links. Communicate changes where needed and monitor not-found reports after cutover before retiring the old routes.
Cloud and web migration support can plan route continuity. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
