A component deprecation warning is a migration signal, not proof that the site's public pages are broken. Locate the custom interface that imports the component and test its replacement against the WordPress versions you still support.
Identify the planned change accurately
The October WordPress developer update lists Divider, ResponsiveWrapper, Scrollable, ZStack and Elevation as deprecated in Gutenberg 24.1, with removal planned for WordPress 7.4. Planned removals should be rechecked against release notes before deployment. The Divider change is one primary implementation reference.
Do not remove a package solely because its name appears in a warning. Several plugins may share the WordPress-provided component runtime. Start with your own source imports and build output, not a global search-and-delete in production files.
Inventory the actual usage
Record each component, the screen containing it, its props and the oldest WordPress version your plugin supports. Identify whether the dependency is bundled or supplied by WordPress. An updated local package does not guarantee that an older site's runtime exports the replacement.
For Divider, inspect whether it is purely decorative or represents a meaningful separation in the interface. For ResponsiveWrapper, record how width, height and surrounding layout currently determine the space. A replacement that looks similar in one screenshot can still collapse when content loads.
Console: Separate warnings from errors. Layout: Test before media loads. Semantics: Keep labels and navigation. Versions: No missing replacement export. Explanatory checklist, not a customer test result.
Replace one responsibility at a time
Use the recommended supported component or ordinary CSS for the behavior your interface needs. A separator replacement and a responsive-media wrapper are different migrations; do not apply one generic wrapper to both.
For an aspect-ratio-based replacement, establish dimensions and test before the media loads, after it loads and with a missing media response. Check that neighboring controls do not jump into the reserved space. If the original wrapper accepted dynamic dimensions, preserve that relationship rather than hardcoding one sample ratio.
For a separator, check the semantic output as well as border styling. Decorative separation should not create confusing focus stops. Keep labels and help text associated with the original controls.
Test a small compatibility matrix
| Environment |
Required observation |
| Oldest supported WordPress |
Interface loads without missing-export errors |
| Current stable installation |
Existing workflows still save correctly |
| Relevant Gutenberg development build |
Warning is removed for your usage |
| Narrow viewport and keyboard navigation |
Controls remain reachable and labels visible |
Keep console errors distinct from deprecation notices. An interface that renders but fails to save is not an acceptable migration. Use a disposable post or settings value, save it, reopen the screen and verify persistence.
Release without hiding the warning
Do not suppress the console globally or remove accessibility behavior simply to produce a clean screenshot. Document the changed import, replacement behavior and version coverage in the plugin's own change record.
Complete the broader staging plugin-update checklist before releasing. If an editor screen is already broken, HandL WP can isolate the package compatibility issue from the affected screen, exact versions and first relevant console error.
