Movable Type Backup Importer Plugin

This plugin allows you to import Movable Type backups instead of exports. It reads the Meta information from the Movable Type XML file and creates the correct objects and relations in your WordPress Blog.

You can import the following contents from your Movable Type blog:

• Posts
• Tags
• Categories
• Users
• Files
• Images
• Comments

Some additional goodies:

• Support for Multisite setups
• Associations between Posts, Tags, Categories & Media
• Updated internal URLs in your posts (Images, Links)
• Users added as authors to blog instance
• Images will be added to the media library (with thumbnails)
• Support chunked backups for importing large sites

Known Limitations

• It’s possible to get an Out-of-Memory Exception while importing, if your XML backup is too large to be processed in memory. Try using chunked backups from Movable Type (e.g. 2MB) instead.

Roadmap

• Try to use information from newly created image library entries, to generate new clean img tags with correct sizing, etc.

1. Unzip movable-type-backup-importer-$VERSION.zip.
2. Upload the movable-type-backup-importer folder to your /wp-content/plugins folder
3. Activate the plugin through the ‘Plugins’ menu in WordPress
4. Go to the Tools -> Import screen, Click on ‘Movable Type (Backup)’

If you have large Backups, try to use a chunked backup from Movable Type, like 2 MB chunks for example. This is important to avoid memory problems during the import.

1. 

   This screen shot show the Tools -> Import screen with the new entry 'Movable Type (Backup)'.

2. 

   The importer shows backups which are located in the correct directory. Later, it will allow you to choose the objects you want to import. Currently, it imports all of them.

Where can I change the Movable Type Backup directory?

You need to add/change a the following line in the cgi-bin/mt-config.cgi file
TempDir /tmp/mt
