Well, I shutdown my old server this morning and removed it. Everything is now migrated to working on this new clean server :)
Also, hopefully, I'll get around to finally setting up IPv6 access to this site as well.
Note that things like http://fscauth-demo.lastyearswishes.com still work. I decided to keep those subdomains on lastyearswishes.com and not migrate them. The eventual course of action though will be that those subdomains are just removed, along with their content from my server
