* Migration class for WANotifier plugin v3 |
| 8 |
* |
| 9 |
* Migration flow (batch — all slugs in one redirect): |
| 10 |
* |
| 11 |
* 1. Migration page shows a list of legacy triggers grouped by integration slug. |
| 12 |
* 2. A single "Connect & Migrate" button redirects the user's browser to the SaaS |
| 13 |
* batch migration page at /integrations/migrate/, passing all slugs, their connect |
| 14 |
* tokens, the old API key, and a return_url. |
| 15 |
* 3. SaaS: shows a single authorization page listing all integrations. The WA account |
| 16 |
* is resolved automatically from the old API key — no account selector needed. |
| 17 |
* 4. User clicks "Connect & Migrate All". SaaS loops over each slug: |
| 18 |
* - Creates a connection row (save_connection). |
| 19 |
* - Calls the plugin's /wp-json/notifier/v1/{slug}/connect to deliver credentials. |
| 20 |
* - Fetches legacy trigger definitions from /wp-json/notifier/v1/legacy-triggers?slug={slug}. |
| 21 |
* - Runs process_migrate_trigger() for each trigger, which saves the new trigger config |
| 22 |
* and updates the corresponding Notifications' trigger references from the old format |
| 23 |
* (e.g. wp_abc12_woo_order_new) to the new format ({connection_id}:{trigger_slug}). |
| 24 |
* 5. SaaS redirects back to the plugin's migration page (return_url). |
| 25 |
* 6. Plugin detects all slugs are connected and shows "Finalize Migration" button. |
| 26 |
* 7. User clicks "Finalize Migration" (AJAX): |
| 27 |
* - Calls /api/v1/disconnect (old API key) to remove legacy trigger schema from SaaS. |
| 28 |
* - Permanently deletes all wa_notifier_trigger CPT posts. |
| 29 |
* - Marks migration complete. |
| 30 |
* |
| 31 |
* Migration state is tracked via the `notifier_migration_status` option: |
| 32 |
* - '' / not set : migration not started |
| 33 |
* - 'complete' : migration done |
| 34 |
* |
