It should be like one line in the IRC server config to change the hostname, then update a few lines to link to other servers in the network, probably new certificates for that, update a few domain name references in the MOTD, maybe edit firewall rules, probably also the round-robin/load balancer config, wait for DNS propagation. The longer-lasting pain will be for channel operators who didn't advise their users where to connect if Freenode goes down, or set up fallbacks.

Well, you see, we need Windows admins, and we find that people who can master the convoluted nuances of the English language are naturally suited.
