+- Add `MIGRATION.md` for upgrading from `beapi/tabs-block`
+- Add PHPUnit coverage for the tabs block migrator
+- Skip block registration when compiled `build/` assets are missing

+# Migrating from `beapi/tabs-block` to `blockparty-tabs`
+
+This document describes how to move from the abandoned [`beapi/tabs-block`](https://github.com/BeAPI/beapi-tabs-block) package to `beapi/blockparty-tabs`.
+
+## Package swap
+
+```bash
+composer remove beapi/tabs-block
+composer require beapi/blockparty-tabs
+```
+
+Activate `blockparty-tabs` and deactivate `beapi-tabs-block` (or `tabs-block`).
+
+## Block model changes
+
+| Old | New |
+|---|---|
+| `beapi/tabs` | `blockparty/tabs` |
+| `beapi/tabs-nav` | `blockparty/tabs-nav` |
+| `beapi/tabs-nav-item` | `blockparty/tabs-nav-item` |
+| `beapi/tabs-panels` | `blockparty/tabs-panels` |
+| `beapi/tabs-panel-item` | `blockparty/tabs-panel-item` |
+| Parent `title` (saved as `aria-label` on the root) | `ariaLabel` on `blockparty/tabs-nav` |
+| CSS `.wp-block-beapi-tabs` | CSS `.wp-block-blockparty-tabs` |
+
+Nested structure (nav + panels, paired nav/panel items) is preserved. Icons inside tab labels keep working when `blockparty-icons` or `beapi/icon-block` is active (`blockparty_tabs_allowed_icon_blocks` filter).
+
+## Content migration (WP-CLI)
+
+WP-CLI only loads **active** plugins. If you see `'blockparty-tabs' is not a registered wp command`, activate the plugin first:
+
+```bash
+wp plugin activate blockparty-tabs
+```
+
+After activating `blockparty-tabs` and updating theme allowlists:
+
+```bash
+# Preview (current site)
+wp blockparty-tabs migrate-from-tabs-block --dry-run
+
+# Apply on the current site
+wp blockparty-tabs migrate-from-tabs-block
+
+# Limit post types
+wp blockparty-tabs migrate-from-tabs-block --post-type=post,page
+```
+
+The command always targets **one site only**. On multisite, repeat it yourself with `--url=` for each site:
+
+```bash
+wp blockparty-tabs migrate-from-tabs-block --url=https://example.com/
+```
+
+The command:
+
+1. Scans `post_content` for `beapi/tabs*` block comments and legacy class names
+2. Parses blocks, converts markup recursively, serializes back
+3. Moves the parent `title` attribute to `ariaLabel` on `blockparty/tabs-nav`
+4. Aligns saved HTML with blockparty-tabs `save()` output (ARIA roles, `is-active` / `is-hidden` classes)
+5. Updates posts with `wp_slash()` on content
+6. Logs migrated / skipped counts
+
+### Revisions
+
+Only the scanned post types are migrated (public REST post types + `wp_block` by default). **Revisions are not included** unless you pass them explicitly:
+
+```bash
+wp blockparty-tabs migrate-from-tabs-block --post-type=revision
+```
+
+### Duplicate Post (Yoast)
+
+If [Yoast Duplicate Post](https://wordpress.org/plugins/duplicate-post/) is active, updating a Rewrite & Republish **copy** via `wp_update_post()` can abort the WP-CLI run.
+
+Preferred workaround: skip that plugin for the migration only:
+
+```bash
+wp --skip-plugins=duplicate-post blockparty-tabs migrate-from-tabs-block --url=https://example.com/
+```
+
+## Front-end checklist
+
+- Update theme allowlists from `beapi/tabs*` to `blockparty/tabs*`
+- Update theme SCSS selectors from `.wp-block-beapi-tabs` to `.wp-block-blockparty-tabs`
+- Smoke-test top alignment and sidebar layouts, keyboard navigation, and nested tabs
