It's one of the best distribution out there for servers, has great GUI toolset, really solid configuration options and easy to upgrade from RHEL or RHEL-based distro to a more cutting edge platform by just doing apt updates. Support is not as large in my country (Eastern Europe) like other distributions with global popularity such as CentOS/Fedora where you almost always get quicker support than here in Estonia. The cost can be prohibitive if your budget does not allow it. Just do a fresh install, make sure you backup everything! And then restore all data back from backups before a new installation. You will not regret this decision when you realize how much faster production goes under this system compared to our old server infrastructure that ran Windows Server 2003 at some point without even realizing why performance was so bad. Faster processing time for every business process related task that we have from ticketing services through development, testing and deployments, etc. I like the fact that its is easy to install and to configure. Also it is very easy to use. The only thing I dislike is that It is very difficult to find the configuration for the firewall, It is very difficult to find the correct configuration of the firewall. Also I don't like that the firewall is very difficult to configure because it is very difficult to find the correct configuration. I like the fact that it is very easy to use and to install. Also I like that it is very easy to configure.
