There are few links where they explain you to install wordpress manually and if you install some old version wordpress then you will have to upgrade it and it is one heck of a work if you are not much into blogging (if you are new to blogging). It was hard to upgrade wordpress from old version to new one last year. But now you can upgrade wordpress automatically. Well it’s not totally automatic. You will have to follow some five steps and the wordpress will be upgraded. Back then the user was supposed to manually remove the old wordpress (by taking its back up) and then install the new one and follow few more complicated steps to make sure that the wordpress was installed properly.
Now you just need a plugin to upgrade the wordpress automatically. People having a wordpress blog will have no problem in upgrading it as wordpress does the upgrade itself if they just click on the upgrade wordpress link and they will need to follow only few steps. But for those who own a domain and run their blog in their domain with wordpress were supposed to upgrade the wordpress manually. But now wordpress has come up with a plugin called wordpress automatic upgrade . Get the plugin and upload it in your plugin folder and then activate it to use it. Thats all. You are ready to upgrade your wordpress anytime. Give it a try.
