Knowledge Base & Operational DocumentationHow to Verify That a Business Email Migration Is Complete
11/10/2026
A migration may appear complete while aliases, shared mailboxes, mobile clients, forwarding, or DNS authentication remain configured on the old service.
Checks to make
Inventory all addresses and mail flows, validate inbound and outbound delivery, check SPF, DKIM, and DMARC, test shared resources and client setup, and reconcile mailbox counts. Retain the prior service until monitored traffic confirms it is no longer needed.
When to get help
Email migration support can verify mail flow and account coverage. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
