Upgrade Kubuntu/Ubuntu using ISO (Without fresh install)

Question

Is it still possible to upgrade Kubuntu /Ubuntu without wiping the root partition?

I mean something like this: Upgrading ubuntu from LiveDVD instead of do-release-upgrade.

This method will be handy in case of unstable internet.

(My current running systems are Kubuntu 17.10 and Ubuntu 16.04 LTS, and I want to upgrade to 18.04 as soon as it's released)

No,

That is not advised any more...

Why?

The CD/DVD Image will not have the entire 1.1TB of Ubuntu Repository files available, so doing an upgrade from CD would give you a partially upgraded system at best.

Sorry! :-(
