I have a VirtualBox headless installation up and running on a Ubuntu Server 14.04 machine. I installed VirtualBox via
apt-get install virtualbox. Now I would like to upgrade this installation to 5.0, and I have seen that it is available via
apt-get install virtualbox-5.0.
Taking into account other related questions in this site, I see that I have to remove my current VirtualBox installation first, but I would like to know if it is possible to upgrade VirtualBox in one step so I wouldn't need to start from scratch registering and setting up all my virtual machines.
