Preserve what already works
Export canonical URLs, organic landing pages, internal links and metadata. Mark the pages that must retain a close destination.
Make redirect decisions by purpose
Map each valuable old URL to the closest equivalent page. Do not send every retired page to the homepage.
Test before release
Crawl staging where access rules permit. Validate navigation, canonicals, robots directives, XML sitemaps and structured data on each template.
Monitor the real launch
Watch server errors, redirect chains and index coverage. Compare priority query groups and landing-page paths instead of relying on one sitewide total.
