2.8.4, the current version of WordPress, is immune to this worm. (So was the release before this one.) If you've been thinking about upgrading but haven't gotten around to it yet, now would be a really good time.

I did the upgrade to 2.8.4 in one fell swoop by following the steps in the wordpress codex. There appeared to be only a few glitches that were relatively quickly ironed out and everything seemed to be running fine.
Until I noticed several stray Âs in some of the older posts. And Ã»s instead of üs, Ã©s instead of és, Ã¢s instead of âs, etc. etc. It turns out that I SHOULD have disregarded the detailed instructions and googled to find others' recommendations about upgrading the Legacy Wordpress. Thank goodness for backups!! (Please read more about my wordpress upgrade woes. )
When you are upgrading your older version of wordpress (don't put it off!!), take a look Pixelita Designs; they put together a handy (if only I'd seen it!!) step by step guide:
- Backup your database! If you have the WP Backup plugin, just use that to capture the latest MySQL dump. Otherwise, go through your web host's control panel and PHPAdmin to export the *.sql file to your hard drive.
- Chart your upgrade path. Since you are upgrading from 2.0.11, you should upgrade incrementally, like this: 2.0.11 > 2.1 > 2.2 > 2.3 > 2.5 > 2.6 > 2.7 > [2.8.4]
- Make sure you have downloaded and unzipped to folders all of the WP versions you'll need to complete your upgrade. You can find them in the download archive.
- Using your favorite FTP program, upload WordPress, starting with 2.1, from the folder you downloaded and unzipped. DO NOT UPLOAD any .htaccess or wp-config.php files from any of the distros! You will want to retain your own versions of .htaccess and wp-config.php already on your server.
- Once the first new version is uploaded, point your browser to the /wp-admin folder and upgrade.php. For example, if your WordPress install is at www.yourserver.com, you would go to: http://www.yourserver.com/wp-admin/upgrade.php.
- Proceed to upgrade the database when prompted.
- Repeat steps 6, 7, and 8 above (uploading the incremental versions, invoking upgrade.php and updating the database) until you've upgraded all the way to [the most recent] WordPress

Obviously, if you are upgrading from Wordpress 2.2, you would upgrade 2.2 > 2.3 > 2.5 > 2.6 > 2.7 > 2.8.4 And please remember to start with making a full backup of your wordpress!!
Also, while you are doing the upgrade, you can upload a temporary index file to your wordpress folder. Make a page that looks like your site and put something like "server currently undergoing maintenance - please come back later" on the page. Save it as index.html and upload it to your wordpress folder. Once the upgrade is done, you can remove that temporary index file and get back to blogging.

Hope this helps.
