Upgrade to WordPress 2.6

It's been over a year since my original WordPress installation.  I started with 2.4, and ignored the 2.5 release.  Since 2.6 was recently released I thought it was time to take the leap.

I followed the upgrade instructions closely. Here's a summary of the experience:

1. The backup and upgrade process was straight forward. The instructions on which files to delete and not delete could have been clearer.
2. Huge gotcha: Lost category and link descriptions. The process for restoring these (WordPress 2.6 Upgrade - Fix Missing Categories) was awful, but at least it worked. If I had known about this before hand I would have waited to do the upgrade until this problem was fixed.
3. All of the plugins I use were upgraded and re-installed without a problem. I like the new integrated upgrade capability.
4. I don't use a custom theme so I did not have to deal with any display issues. The new wp-syntax plugin improved code formatting looks great.
5. The only customization I had to do was add my LinkedIn link to SideBar.php and the Goggle Analytics script to Footer.php.
6. For some reason the sub-domain link to the blog (http://blog.bobonmedicaldevicesoftware.com) goes directly to the main domain http://bobonmedicaldevicesoftware.com.  I'm sure that my root .htaccess file didn't change so I don't understand why this is now happening. I haven't been able to find a solution yet, so in the mean time I've just re-directed the main page back to the blog.

That's it. Hopefully the new 2.6 features will be worth the effort.

UPDATE (8/15/08):

Upgraded to WP 2.6.1 using WordPress Automatic Upgrade 1.2.1.   WPAU automates WP and database backup, puts the site into maintenance mode, disables all plugins, does the WP new version upload and unpacking, database upgrade, and re-enables plugins.  This update wasn't really necessary for me, but I wanted to walk through the automatic upgrade process just to see how it went.  Everything worked fine, which was expected for a minor release.

I don't know if problem #2 was resolved for 2.6.1 upgrades from older WP versions.  I did a quick read-through of the fixed bugs, but that one didn't jump out at me.

UPDATE (12/13/08):

Upgraded from WordPress 2.6.5 to 2.7 with WPAU. Worked great. The new 2.7 admin interface is nice and the built-in updates will hopefully work as well as WPAU.

I also just noticed that my problem #6 -- sub-domain link to the blog -- has been fixed in WordPress 2.7. WooHoo!
