Upgrading the Distro

Hi,



I'm running custombuild 2.0 now.



Is it possible to upgrade my distro from currently Debian 7.7 to 7.8 without affecting or messing current configurations?



With apt-get dist-upgrade ?



Or perhaps there's another way to safely upgrade it?



Or is it not recommended to do so?



Any help would be appreciated.



Cheers!
