ubuntu + ISPConfig and moving from shared hosting
i am trying to move 5 Wordpress websites from shared hosting to Ubuntu with ISP Config. what is the best option ? I have Ubuntu 15.04 and want to install ISPConfig but first I need to have a domain? So what domain I have to use? I dont want to have some downtime on all websites.
Can you give me some good advice if I have to buy some new cheap domain which will be the main for this server and after move all files and connect database and in final change nameservers to digital ocean ? thanks
