I am starting a business and have chosen wordpress for what will soon be 50+ websites. Multisite sounds perfect but the documentation I have found in the Codex has a lot of warnings about making any big changes after Multisite is setup for longer than a month.
My question: If I get started with a simple web host that uses my http://www.domainname.com address and the subdomain (vs path) configuration of Multisite, will there be any trouble when I want to transfer the site to a dedicated server in a couple of months? The domain name won't change at all, just the physical server.
Any help would be most appreciated!
