Plesk 12.x. How to Debian update?

[VangDo]

Hi,
Is it possible through Plesk Linux version on the root servers to update?

If not and you will update the Debian itself, you have to note something?
What should you back up before everything to make Plesk is working again?
Is a complete reinstallation is required?

Thanks.

Just for your information:

Plesk does not support major OS upgrade (dist-upgrade).
