Technical Site Migration
& Domain Change Playbooks

A site migration is one of the highest-risk operations in web infrastructure. A single misconfigured redirect, a premature DNS flip, or an overlooked canonical tag can wipe out years of accumulated search equity in 72 hours. These playbooks exist to prevent that.

Each guide is written for practitioners — not theorists. Every section contains exact server configs, CLI commands, validation checklists, and rollback protocols you can execute the same day. Whether you are consolidating domains, replatforming a CMS, or restructuring a URL taxonomy, the sequence below will get you through it without surprises.

Start with the auditing playbook to capture your baseline, work through URL mapping to lock in your redirect architecture, then execute the DNS cutover with a tested zero-downtime plan. Every phase links to the next so nothing falls through the cracks.
