I recently acquired a large website containing roughly 2,000–3,000 static HTML files. It still receives some traffic, but rankings and visits are declining because the content is outdated and the design is not mobile-friendly. I'm considering moving the site to WordPress or another CMS and would like to do it fairly quickly without damaging organic traffic, backlinks, or domain authority. What migration process would you recommend, especially regarding URLs, redirects, content, and rollout strategy?

Expect some short-term fluctuation, even with a careful migration. Preserve the existing titles, headings, body content, canonical tags, metadata, internal links, and URL paths wherever possible. Test the process on a small group of lower-performing pages first, monitor rankings and traffic, then expand the rollout gradually.
Start with a complete crawl of the current site and export every URL, title, meta description, heading, canonical, status code, and important internal link. Keep the same URL structure in WordPress if you can. For pages that must move, create a precise one-to-one 301 redirect map rather than sending everything to the homepage. Put the new site on staging, test crawling and redirects, and only then change DNS.
Don’t treat this as just a technical CMS swap. First audit the content and identify pages worth keeping, updating, consolidating, or removing. Moving thousands of outdated pages unchanged may preserve URLs but won’t necessarily solve the traffic problem. A content strategist or experienced SEO could help decide what should actually be migrated.
You can import the existing HTML into WordPress pages and customize the permalink settings to match the old paths. If the old URLs end in .html or use another unusual pattern, server rewrite rules and redirects can accommodate that. Before launch, compare the new pages against the crawl of the old site and check for broken links, accidental noindex tags, missing canonicals, and redirect chains.
A site with only static content may not need WordPress at all. A static-site generator could provide a modern responsive design while keeping the site lightweight. The important parts are preserving URLs, content, metadata, and redirects—not the specific platform.
