I'm trying to change my multisite's domain name. And, I've read several threads on doing this (clear as mud). From what I'm seeing, a "find and replace" of the old domain name with the new is essential. However, how does one do that in phpMyAdmin? Several (far more proficient) responders have mentioned doing a "database dump." I don't know what that is. So, if someone has a step-by-step method for me to achieve this "find and replace" task, I would be very grateful. (There really does need to be a step-by-step procedure/manual to change multisite domains.)
Thanks in advance!
