Ok, here is the thing. I have two exactly same servers and I finished the entire configuration of server number one (Apache, MySQL, postfix...).

I did also a lot about security and now i wanna migrate server configuration to server number two, where I have installed same Ubuntu server 14.04.

Any suggestions?

If the servers are completely identical, disk cloning is the easiest solution.

Just use any disk cloning utility (there are lots of them around); in a pinch, even dd will do.

If you have a hardware RAID-1 configuration, you can also take a disk from the first server, put it in the second server, and rebuild the mirror on both machines; you'll end up with two identical servers.

  • With disk cloning, your UUID's for your disks will be identical, which could get your intro trouble later. The RAID1 approach wouldn't have that problem.
