WordPress

WordPress is an open-source content management system built primarily with PHP and a database, commonly used for blogs, marketing sites, publications, membership sites, and online stores. Its administration interface lets non-developers create content, manage media, configure navigation, and administer users, while themes control presentation and plugins add features. It can run as a traditional server-rendered site, expose content through APIs for a separate frontend, or support a mixed approach. Its large ecosystem is a major strength, but it also means that a WordPress installation is often a combination of core software, a theme, custom code, plugins, hosting configuration, and externally managed services. WooCommerce is a plugin that runs on WordPress, so a WooCommerce store is a WordPress site, and its WordPress version matters to it just as much as its WooCommerce version does.

WordPress began as blogging software and developed into a general-purpose publishing platform. Early development emphasized posts, categories, themes, comments, and an approachable administration experience. As adoption expanded, the project added a more formal extension architecture, custom content types, richer media handling, user roles, menus, APIs, and editor capabilities that made it suitable for broader site-building use. Later development moved toward a block-based editing and site-building model, while the older editor and many traditional theme patterns remained in widespread use. This long history has produced a large installed base with sites built according to different architectural eras, from simple blog themes to heavily customized editorial platforms and stores.

Migration planning should begin with an inventory of the actual installation rather than treating WordPress core as the whole application. Content can be relatively portable, but its meaning is often encoded in custom post types, taxonomies, custom fields, shortcodes, page-builder data, reusable blocks, and plugin-specific database tables. A target platform may need explicit content models and transformation rules for each of these. Themes can contain business logic, custom templates, editor integrations, and direct database assumptions; a visual redesign does not automatically reproduce those behaviors. Plugins may provide critical functions such as forms, search, multilingual content, redirects, memberships, ecommerce, SEO metadata, caching, and integrations, and replacing them usually requires data extraction as well as feature work. Media migrations need to account for file paths, image derivatives, embedded references, captions, permissions, and storage or CDN arrangements. URL structures, redirect rules, canonical URLs, structured metadata, sitemaps, and historical attachments are important for preserving search visibility. Sites moving into WordPress face similar questions in reverse: imported data must be mapped into WordPress content structures, the chosen editor and theme approach must be compatible with the intended authoring workflow, and required plugin integrations must be tested together. Legacy PHP, database, server, and plugin dependencies can constrain upgrades or hosting moves, while custom code that bypasses WordPress APIs can make those constraints harder to identify. For WooCommerce sites, plan separately for products, variations, attributes, orders, customers, taxes, shipping rules, payment records, subscriptions or other extension data, and privacy or retention obligations; data that must remain available for operations or compliance should not be assumed to fit a simple product-and-order export.
