Covers seven signals that indicate a platform is actively holding back the business, a decision framework for choosing between rehost, refactor, replatform, or rebuild, and a detailed comparison of strangler fig vs. big-bang migration approaches. Includes a five-phase modernization roadmap with hard exit criteria, data migration integrity practices (idempotent jobs, reconciliation checksums), SEO equity preservation via validated 301 redirect maps, and PCI-DSS compliance continuity using blue-green deployments.

Destination stacks covered include Shopify Plus, commercetools, VTEX, Saleor, and SAP Commerce Cloud paired with headless CMS options like Contentful and Storyblok. ## Full article daily.dev links to this article rather than hosting it.
