Direct Upgrade Ubuntu from 9.04 to 9.10

Ubuntu upgrade from 9.04 to 9.10 can never be easy like this:

Before the actions, it is essential to backup any running database and web server for disaster recovery and then turn them off completely.

You can easily upgrade over the network with the following procedure.

1. Start System/Administration/Update Manager

2. Click the Check button to check for new updates.

3. If there are any updates to install, use the Install Updates button to install them, and press Check again after that is complete.

4. A message will appear informing you of the availability of the new release.

5. Click Upgrade.

6. Follow the on-screen instructions.

Finally, reboot the system and see all changes.

There was compatibility issue regarding XAMPP package since people complained they couldn't get XAMPP based server startup after the reboot. In my case, it did happen before. In recent trial of GUI upgrade directly from Ubuntu Update Manager, the problem seems to be solved. I have even got another notice from Update Manager about Ubuntu upgrade to version 10.04 as well.
