This information is correct, but not complete:  the only upgrade path
from 7.04 is to 7.10. Saurabh will then need to upgrade from 7.10 to
8.04 very soon, because 7.10 will itself reach end-of-life in April
2009.

It's probably better to back up all important data to another system,
e.g., an external disk, and reinstalling a new Ubuntu.

IF Saurabh wants to perform the upgrades instead, he should first change
his software sources to http://old-releases.ubuntu.com/ubuntu/
This ensures that the last updates that were available for 7.04 are
applied - these might be required for a successful update to 7.10.
Saurabh, ask if you don't know how to do this.

After the updates are applied and the backup done, you can run System ->
Administration -> Update Manager. Then click the "Check" Button and wait
until the option to upgrade is offered. Follow the instructions.

Then repeat the last step (Upgrade Manager) to upgrade 7.10 -> 8.04.

For what it's worth, I think that the fact that a user does not get
informed by the system about reaching end-of-life status is a serious
bug. A report is open here:
