How do i upgrade a system where isp config is running on ?

Hi

Maybe a silly question.
But got this from the monitor function inside ispconfig :

Reading package lists...
Building dependency tree...
Reading state information...
The following packages will be upgraded:
dpkg dpkg-dev dselect libapache2-mod-php5 libcups2 libcupsimage2
libmysqlclient15off linux-image-2.6.26-2-686 linux-libc-dev mysql-client
mysql-client-5.0 mysql-common mysql-server mysql-server-5.0 php-pear php5
php5-cgi php5-cli php5-common php5-curl php5-dev php5-gd php5-imap
php5-mcrypt php5-mysql
25 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Is it not critical to update that ?
And after you have run :

apt-get update

What would the next command be ?

Next command to install upgrades is: apt-get upgrade

Or just run "apt-get" to get a list of options.

 

Hi

Thanks for your answer so far, really appreciated.
Can this update command be done without problems on a running live system ?
And are there any precautions to make before update ?
