Upgrading to Ubuntu Server (i386 or amd64) is easier than you might think! You don't have to reinstall the entire operating system to get your server running the latest release of Ubuntu Server 10.04 LTS. Below are the steps to make it happen. But of course before you do, you should always do your homework!
Sometimes when running a server you have specific requirements for your software. Doing an upgrade like this can and will most likely change those to the latest and greatest revision's. This can go two ways, really really bad or really really good. It all depends on your requirements. Luckily before the upgrade happens, the below method will tell you what is about to happen and what is going to get upgraded. So be sure to pay close attention to what it tells you! It's also a good idea to perform a regular aptitude update & upgrade before performing this operation, but not required. And as always, BACKUP your data. No matter what! Always leave yourself a path to get back to your server incase anything goes wrong!
$ sudo nano /etc/update-manager/release-upgrades
Prompt=normal
- Install update-manager-core if it is not already installed
$ sudo aptitude install update-manager-core
- Edit /etc/update-manager/release-upgrades and modify the "prompt" value.
- Launch the upgrade tool
$ sudo do-release-upgrade - Follow the on-screen instructions, this is where it will display what is going to be changed and so on.
Happy Upgrading!

Yes… doing a full backup will be the safety option.
but… I have now 9.04 ubuntu server, what will be improved with the 10.04 version….? I mean, it’s worth upgrading??
The answer is yes and no, it all really comes down to how an application is configured and how it was originally installed.
If you installed them via the ubuntu repos, they will usually update with the system (via an upgrade or OS upgrade) just fine. But custom configured portions can sometimes stop working, but shouldn’t be too difficult to get working again if they do go a little crazy after the update.
If you compiled something via source, dependencies usually change and you may need to recompile them. But your configuration will usually continue to work after.
But like I said, it all depends on many different factors. This is why I always suggest installing anything in ubuntu via the repos if possible. In any case, just make a full backup of your harddrive and perform the update to see how it goes. That’s the safest way to go.
Hi. I like your blog, i have found usefull information here.
