Hello, everyone. I've been lurking on this forum for a while but have never needed to post asking for a bit of help until now.
Long story short, I have a test of sorts scheduled with a prospective employer, a managed web hosting company, that involves migrating a hypothetical customer from their old server to their new server, hosted with the prospective employer. I have worked with Linux for a few years now, including at two unmanaged hosting companies for about three years, so I can handle the basics and a bit of intermediate stuff without any issue.
Unfortunately, due to my past jobs offering
unmanaged hosting, we would never in a million years do something like this for a customer, so I am not familiar with how to do this. I know how to move data, users, and so forth over, basically via what is mentioned
here, which we also would never do, due to learning on my own time. However, the stipulation that services on the origin server
not be shut down during the migration process, which entails moving services over as well, has me scratching my head, hence my request for help or a few pointers regarding live services migration.
What I know about the impending test is that it "is a standard configuration not designed to be tricky." This is for web hosting, so I assume it will have Apache, MySQL, PHP, a mail server, and other basic web hosting services running. As far as the distro, it is either going to be CentOS, which I am most familiar with, or Gentoo. The person I was e-mailing could not remember which distro it was.
Any and all assistance regarding live server migration will be greatly appreciated, because how I perform on this test will likely determine if I remain laid off in Dallas or employed in New York City.
