b2evolution to WordPress migration

I’ve been looking for b2evolution to WordPress importer for long time. What I can find on the web are only migration script for older version of b2evo/wp, hence I’ve decided to write one on my own, for importing data from b2evolution 4.0.5 to WordPress 3.7.1. I’ve tested the script with WordPress 3.8.0 too. I’m hereby sharing it to whoever needs it.

Instruction

  1. Place this file at the same directory with your wp-config.php
  2. Access the URL at web browser, e.g.: http://localhost/b2wp.php
  3. Fill up the form with database connection detail, and submit.
  4. Select import options, and start import.

Warning

  1. Backup all your databases safely before proceed.
  2. Try it with a fresh installation of WordPress instead of production site.
  3. Use this script at your own risk 🙂

Download

  • b2wp.php – Tested with b2evo 4.0.5 to wp 3.7.1/3.8.0
  • b2wp_kp.zip – provided by KP for b2evo 5.1.2 to wp 4.

This is NOT a WordPress importer plugin, this is simply a PHP script to extract content (Authors, Categories, Posts, Tags, and Comments) from a b2evolution database and insert into WordPress database. This migration script does NOT catered importing of uploaded media files. Feel free to modify it as per your needs. You might want to try these WordPress plugins Add From Server or Import External Images for migrating your uploaded files.

Special thanks
Thanks to RealNitro’s b2evo2wp.php script, it was my primary source of reference for understanding b2evo/wp database schema.
Thanks to KP for sharing b2evolution 5.1.2 to WorPress 4 migration script.

2014 – A new beginning

Yes I know I know, this site was missing for several months. Losing visitors/readers, site pagerank dropped to zero, pages totally been removed from Google index, this is definitely not what I wanted to see.

Blog comments flooded with spam, web hosting plan (with 1TB monthly bandwidth limit) been suspended due to “overuse”, I’ve been tied up with work, couldn’t squeeze in some time for fixing this issue, until I was required to use my year end leave.

Not mentioning what the reason, I’ve decided to migrate the blog from b2evolution (b2evo) to WordPress (self hosted), I’ll share the migration script later, migrate from shared hosting service to Google App Engine (GAE). I’ve deployed WordPress multisite up there. Look! on the cloud ^^

This is just a beginning, a new beginning. There are still enhancements required, many things to be learned, and hopefully more to be shared too.

Over Quota

Last but not least, a belated new year greeting, Happy 2014… Happy 2013A for those who avoiding inauspicious number “4”, Happy 2013S for those who believe suffix S means something better although it is the same, happy new year for all 🙂
