Xenial Xerus upgrade on Asus EEE PC 1000H

Hello.

My friend has Ubuntu, the previous LTS, installed on her Asus EEE PC 1000H laptop. She is considering to upgrade to Xenial Xerus. Are there any guarantees if the upgrade succeeds, and whether it works well enough?

The current LTS Ubuntu works on the laptop, it is really slow but works.

The laptop has 2 GB RAM, 120 GB Kingston SSD, GPU is probably Intel GMA.

Has anybody else experiences on running Xenial Xerus on EEE PC 1000H?

What are the possible problems one should expect when upgrading and after the upgrade (if it succeeds)?
