How to migrate from another alt text plugin to Bialty
Switching alt text plugins is usually simpler than people expect, but the ease of migration depends entirely on what your previous plugin did. A bulk Media Library updater leaves permanent changes in the database. An AI generator stores descriptions in metadata. A dynamic injection plugin leaves nothing behind. The migration path is different for each case.
Migrating from a bulk Media Library updater
If your previous plugin wrote alt text values directly into the WordPress Media Library (_wp_attachment_image_alt in wp_postmeta), those values are stored permanently in your database. They do not disappear when you deactivate the plugin.
When you activate Bialty, the existing Media Library alt text is still there. Bialty's behavior depends on your rule configuration. If you set Bialty to only fill in missing alt text, images that already have a Media Library value will keep it. Bialty will only inject on images where the stored alt text is empty. If you set Bialty to replace existing alt text, the injected value will override whatever the previous plugin stored, but only in the rendered HTML — the Media Library value itself stays untouched.
The practical migration steps are: deactivate the previous plugin, install and activate Bialty, choose your rule (focus keyword, title, image name, or combined), configure whether to act on missing alt only or on all images, save and check the frontend HTML to verify.
If you want to keep the old plugin's stored values as a fallback, configure Bialty to act only on missing alt text. This way, images with existing values retain them, and images with empty fields get Bialty's dynamic injection.
Migrating from an AI alt text plugin
AI plugins typically store their generated descriptions in the Media Library, just like bulk updaters. The migration path is the same: deactivate the AI plugin, install Bialty, and configure the rule.
The specific consideration with AI plugins is that you may want to preserve the AI-generated descriptions on certain images where they are genuinely good. Configure Bialty to act only on missing alt text, and the AI-generated values will persist in the rendered HTML (because WordPress renders the stored Media Library value by default). Bialty will then fill in the gaps — images that the AI plugin missed or skipped.
If the AI plugin generated poor-quality descriptions that you want to replace, configure Bialty to replace existing alt text. Bialty's contextual rule will override the stored AI descriptions in the rendered output while leaving them intact in the database as a fallback.
Migrating from another dynamic injection plugin
If the previous plugin also used dynamic injection (changing rendered HTML without storing values), deactivating it removes all its alt text output immediately. There is nothing stored in the database to preserve or conflict with.
Activate Bialty, configure the rule, and the transition is instant. There is no overlap period, no conflicting output, and no cleanup needed.
What to check after migration
After switching, verify the result on the frontend. The correct proof layer is the rendered HTML, not the Media Library. Open several representative pages — a blog post, a page, and a WooCommerce product if applicable — in an incognito browser window after clearing cache.
Inspect the <img> tags and confirm that the alt attribute contains the expected value. If it matches your Bialty rule, the migration is working. If it shows the old plugin's value, Bialty may be configured to preserve existing alt text — which could be the correct behavior if you want to keep the previous values.
Check edge cases: pages built with page builders, custom post types (requires Pro), WooCommerce galleries and related products (also requires Pro), and pages that were in the old plugin's exclusion list.
Potential conflicts
Bialty and another alt text plugin should not be active simultaneously on the same filter hooks. If both plugins hook into the_content with similar priority, the output is unpredictable — one plugin may overwrite the other's changes depending on execution order.
Always deactivate the previous plugin before activating Bialty. If you want to test Bialty in parallel, use a staging environment rather than running both plugins on the same production site.
When migration is not the right move
If your current plugin has already produced high-quality, image-specific alt text that you are happy with (especially from a thorough AI generation pass followed by manual review), there may be no reason to switch. Bialty's strength is coverage and consistency from existing context, not image-specific descriptions from visual analysis.
Consider Bialty if your current plugin requires an external API you want to eliminate, charges per image and the cost is unsustainable, created bulk database changes you cannot easily undo, does not cover WooCommerce adequately, or needs to be simpler for agency deployment across multiple sites.
The migration safety net
The single biggest advantage of migrating to Bialty is that Bialty does not write to the database. If the migration does not work as expected — wrong rule, poor coverage, theme conflict — you deactivate Bialty and everything reverts to the previous state. That is the dynamic injection model working as designed: zero residual risk.
No other migration path in the alt text plugin space offers that level of safety.
