Description

PhilDesigns WP Migration Toolkit provides a three-step admin workflow for migrating content between WordPress sites — without needing external tools or direct database access.

Step 1 — Bulk Author Assign (run on the source site)

Upload a CSV of URLs to find and reassign matching posts and pages to a specific author. Then use WordPress's built-in Tools → Export filtered by that author to get a targeted WXR export. Includes a Dry Run mode to preview matches before committing.

Step 2 — WXR File Splitter (run on the source site)

Upload a WXR export file and split it into smaller chunks to avoid server timeouts on import. Each split file carries the full WXR header so WordPress treats every part as a valid standalone export. Download all parts as a single ZIP.

Step 3 — URL Migration Checker (run on the destination site)

After importing all WXR parts, upload your original URL list to verify every page exists on the new site. Supports old-domain replacement so URLs are rewritten before checking. Export missing URLs as a CSV to investigate stragglers.

Features:

• No HTTP requests — all checks run directly against the database
• Dry Run mode for author assignment
• Configurable chunk size for WXR splitting (5–200 items per file)
• ZIP download of all split files
• Export missing URLs as CSV
• Nonce-secured forms and file downloads
