Upgrading Wordpress 2.3 to 2.5 Warning!

If you are considering upgrading your wordpress account and you use ultimate tag warrior for all your tagging then be warned you will lose all your tagging in the new version of 2.5.1 I am currently going through all my previous posts to tag them again. This is proving to be a nightmare. Apparently if you install the simple tags plugin this will work with 2.5 however it will not back tag all your old posts that were originally tagged with ultimate tag warrior. When you try and install the plugin for ultimate tag warrior you get a fatal error as this plugin is not compatible with 2.5. For warned is for armed as they say, there is an option to import your tags before you upgrade by changing your plugin to simple tags before the upgrade and then import all the tags from ultimate tag warrior. If I had known this to start with I would most certainly have done this. Also when importing my database the wordpress 2.5.1 version has changed some of my posts as it doesn't seem to recognize some of the ' & ? symbols, and instead leaves some symbols ie where I have the word don't in a post it ends up with a little tm like a trade mark symbol and some other symbols really weird stuff. There are a few other issues with 2.5.1 so if you are going to upgrade I suggest you check all the plugins you currently use to ensure that they are 2.5 compatible. Wordpress are always upgrading and there comes a time when you have to ask is it really worth the aggravation for the newer version. I say yes as its always good to keep up with changes in wordpress. Sometimes though it is good to wait for the tested versions, ie like maybe when 2.5.2 comes out it will have some bug fixes in it.
