Migration kit + checklist · Builder's Library

The Migration Survival Kit

Move off a legacy CMS without losing the rankings you already earned — the inventory, the redirect map, and the proof.

Most traffic lost in a replatform is lost in the redirects, not the design. Every indexed URL on the old site is an asset you already paid for; a migration either carries that equity across or sets it on fire. The playbook explains the stakes; this kit is the procedure that keeps the equity.

The work happens before you launch. The kit starts with an inventory lock — a frozen list of every URL search engines know about — then maps each one to its new home, one to one, so nothing relies on a wildcard guess. The Search Console checklist and the post-launch validation pass turn "we think it worked" into "we can see it worked," within hours of the flip.
