AI-Generated Code: Quality, Portability and What It Means for Migration

What generated projects do well

Modern builders produce responsive layouts, consistent spacing, accessible component primitives and sensible semantic elements by default. They also produce a coherent design system, because the model applies the same tokens everywhere. For a migration, that consistency is a gift: extract the tokens once and the whole site follows.

The code is usually readable. Component names describe intent, files are small, and formatting is uniform. Reading such a project to recover its content model is considerably easier than reading a decade-old bespoke theme.

Where the friction is

The first issue is duplication. A model asked for three sections often writes three similar components rather than one component used three times, because each request was answered independently. Before extracting templates, consolidate: find the repeated shapes and treat them as a single content type.

The second is hard-coded content. Text, image paths and lists frequently live directly in the components. Every one of those is a field waiting to be defined, and enumerating them early prevents the common outcome where the new site is beautiful but not actually editable.

The third is the metadata gap. Generated sites tend to ship a single title and description for the whole application, no canonical strategy, no sitemap and no structured data. This is additive work during migration rather than preservation work, and it should be budgeted as such.

Keeping a generated site portable

Four habits keep the exit cheap. Connect version control on day one so the export is never a single download. Keep content in data files rather than inside components where possible. Avoid platform-specific hosting primitives for anything that could be standard. And run the build locally at least once before the project matters, because a project that only compiles inside the builder is not really yours yet.

Teams that follow these end up with a normal codebase that happens to have been written quickly, and their migration is an ordinary framework conversion rather than a rescue.

From generated project to maintainable templates

The conversion sequence that works: extract design tokens into theme styles, consolidate duplicated components, define content types from the props you found, build templates for each, import content into fields, then map routes to permalinks. Verify with screenshot comparison at multiple widths and a full URL diff.

Done in that order, a fifteen-page generated site is usually a two- to three-day job including quality assurance — and the result is something an editor can run without touching code.
