Senior WordPress & SEO Specialist Needed: Full Domain Migration & 1-to-1 301 Redirect Setup

We are executing a full domain migration from our current primary domain (stpetecriminaldefense.com) to our new primary brand domain (FletcherTrialLawyers.com). Our goal is NOT simply to set up a domain-level forwarding rule. We want to fully migrate the WordPress installation and hosting primary address to FletcherTrialLawyers.com, so it becomes the main live site, while executing a flawless 1-to-1 301 redirect map to transfer 100% of our established SEO authority, PageRank, and backlinks. Scope of Work & Deliverables Required: Pre-Migration Benchmark & Crawl: Perform a full site crawl using Screaming Frog or similar to create an inventory of all active live URLs, internal links, canonical tags, and XML sitemaps on stpetecriminaldefense.com. WordPress Site & Primary Domain Re-configuration: Update the WP Engine / web host primary domain settings, WordPress Site URL, and Home URL to [https://FletcherTrialLawyers.com](https://FletcherTrialLawyers.com). Perform a global database Search & Replace (using WP-CLI or Better Search Replace) to replace all internal links, image paths, media uploads, and assets from stpetecriminaldefense.com to FletcherTrialLawyers.com. 1-to-1 Server-Level 301 Redirect Strategy (Crucial): Implement page-level 301 (Permanent) Redirects (at the server level/Nginx/WP Engine rules). Rule: Every single URL on [stpetecriminaldefense.com/](https://stpetecriminaldefense.com/)[page] must redirect directly to its exact equivalent on [FletcherTrialLawyers.com/](https://FletcherTrialLawyers.com/)[page]. Avoid catch-all redirects to the homepage and eliminate any potential redirect chains or loops. SSL, Canonical Tags, and Search Console Setup: Ensure SSL certificates are fully active and forcing HTTPS across FletcherTrialLawyers.com. Update all canonical tags across the site so they reference FletcherTrialLawyers.com (no self-referencing links to the old domain). Set up and verify the new domain in Google Search Console. Execute Google’s official "Change of Address Tool" inside Search Console from stpetecriminaldefense.com to FletcherTrialLawyers.com. Generate and submit the new sitemap.xml to Google Search Console. Post-Migration Audit & Verification: Crawl the new domain post-launch to verify there are zero broken links (404s), no noindex tags left over, and that all redirect hops are single-step (301).
