——————————————————————— – OVERVIEW / THOUGHT PROCESS – ——————————————————————— This experiment was conducted on a CentOS 6 installation of Linux. As always, with any other installations of Linux, there may be slightly different commands and directories to consider, but the theory is the same. Try it out if you like the concept… WHY NOT?!? This experiment.

In this scenario, I have two separate CentOS servers with two different public IP addresses. Both have SSH enabled through the firewall and I need to move multiple websites from server.
