Debian: Stretch(ing) to Buster

I had this on my TODO list for quite sometime, so, this a lousy grey, rainy Sunday that kept me from pedaling seeing the GF, thought of it as an ideal day to undertake this monumental task...

- Updated the system on Stretch.

- Edited the file /etc/apt/sources.list, changed "stretch" for "buster".

- Updated the system: sudo apt update

- Upgraded the system: sudo apt upgrade

- Full upgraded the system: sudo apt full-upgrade

- Reboot

- Profit

Everything seems to be running just fine, but I have to configure some stuff (for instance adding the Genmon plugin to the XFCE Panel).
The whole thing took about two hours, and it downloaded something like 1 GB of files.
