I have just installed Multi-DB on my new multisite, which is currently hosted on a VPS. If my site grows as expected, I will be upgrading to a dedicated server within the next year, which will have a different IP address to the one I am using now. My question is this - when configuring and installing Multi-DB it specifically asks for the IP address on which the wordpress databases are installed. If I change IP address, will the databases that Multi-DB has created still work. In other words, how easy is it to migrate a Multisite operating Multi-DB from one server to another?
