Library Migrator Released for Umbraco 18 Migration
A developer recounts attending Codegarden 2026 and discusses Umbraco's new Library feature in version 18 — a Library section and element picker for reusable content — and explains that adoption depends on migration tooling. GrowCreate has released a Library Migrator package that moves documents from the old Content area into the new Library, swaps content pickers for element pickers, and rewrites stored references across block lists, block grids, rich text blocks and base document properties. The package is available now (links to Umbraco Marketplace and a GitHub repository are provided). The author argues migration tooling must be available at release to capture upgrade momentum from live production sites.
Migration tooling enables adoption of Umbraco 18's Library feature for existing production sites; relevant to developers, CMS implementers and marketing teams but not industry-shifting.

Chicago Agency Guide to Hyvä Theme Migration
Towering Media, a Chicago Magento and Adobe Commerce agency, published a detailed migration framework for moving Magento stores from Luma or legacy frontends to the Hyvä theme. The guide explains why Hyvä improves Core Web Vitals (CWV) and site performance by replacing Knockout/RequireJS with Alpine.js and Tailwind, and documents a five-phase migration approach: discovery, planning, build, QA/performance verification, and launch/stabilize. It covers extension audits, checkout strategy (Hyvä Checkout, React Checkout Pro, or temporary Luma fallback), template mapping, image/asset optimization, CWV acceptance criteria (LCP, CLS, INP), load testing, and post-launch monitoring. The article includes anonymized client results (notable LCP and JS reductions and conversion uplift) and practical operational advice such as budgeting for extension rewrites and maintaining rollback plans.
Contentful Model Simulator v0.3.0 Released
A developer published content-model-simulator, a local-first simulator for Contentful content models (v0.3.0). The tool lets teams define schemas locally, point at real or mock data, and preview entries, references, validation errors and model graphs in a browser without modifying a live Contentful space. v0.3.0 adds a from-migrations subcommand that converts contentful-migration scripts into local cms-sim schema files (no Contentful connection required). The project is pre-1.0 (targeting v1.0.0 by the end of May) and is explicitly a simulator — not a migration runner — intended to reduce risk and speed iteration when designing or migrating Contentful models. The code is hosted on GitHub and the package is published on npm.
Adobe Commerce Cloud Hits $40k; Magento Open Source Migration
Authors report Adobe Commerce Cloud license pricing crossed $40k/year for many mid-market merchants in 2026, prompting three clients to consider migrating to Magento Open Source. They executed all three migrations: two were cost-effective and one was not. The post details technical and commercial pitfalls — notably the catalog schema difference (row_id vs entity_id) that breaks direct SQL queries, deep dependencies on Adobe B2B Suite and Adobe Sensei, Page Builder content drift, and non-trivial hosting work when moving off Adobe’s managed platform. A 5-year cost comparison shows potential savings for merchants with in-house or long-term dev partners but higher up-front migration and rebuild costs for organizations dependent on Adobe-only modules. The author provides a decision framework, recommended pre-migration audits, and realistic timelines for DevOps and rebuild work.
