Dare to Upgrade?

My friend in Jogja Linux User Group has sentenced that it was easy to upgrade from kernel 2.4.x into 2.6.x in Slackware. I was quite suprised, since i thought the process will be much more harder. Perhaps Patrick has made them easy with the use of the pkgtool. The only question is do i dare to upgrade to kernel 2.6.x? Not in the mean time. I have to make sure that everything will be OK before i do such process.
