Knowledge Base & Operational DocumentationHow to Review DNS Changes Before Moving a Website to a New Web Server
11/10/2026
A web server move can overlook subdomains, certificate validation records, mail services, and external integrations in the same zone.
Checks to make
Export and categorize current records, identify owners and destinations, and test the new server with the intended hostname. Plan TTL and rollback, preserve non-web records, and verify each important hostname after cutover.
When to get help
DNS and hosting support can coordinate record review and migration. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
