I’ve just upgraded the site to use the new WordPress 2.
Everything seems to have gone smoothly, although i took a slightly different route to the upgrade than they recommend in their documents.
The only thing i did differently was to upload the new version to its own directory (choronzon2), then I copied the plugins and the theme from the old version into the correct places in the new version.
I did this so that I would have a quick escape route back to the old version should anything go wrong. (Of course, I backed up *everything* first). To backup the database I used MySql admin running locally and connected to the remote database rather than installing PhpMyAdmin just for backing up..although PhpMyAdmin is a great tool if you have more involved database management needs.
I dont have a huge amount of plugins running and I had already tested them with a local installation of V2 on my home computer. (I use broobles simple tags plugin for generating [tag]technorati[/tag] tags and my own del.icio.us link generating plugin)
Once I had uploaded all the necessary files the upgrade process itself was incredibly easy (like installing wordpress, but with even less to do).
All that was left was to rename the original directory to choronzon-old and rename the new directory to put it in the right place.
Easy.
If you are wondering about making the move from an earlier version of wordpress I can definitely recommend it if you want to take advantage of the new features. I decided to upgrade because I much prefer the post / page editor in the new version. Having a window to edit the actual HTML is vital when entering pages with a lot of content so I can avoid the auto-formatting process that wordpress applies to the content.
