Alright, at this point the forum is running on the new database, but if you see the big blue message across the top then you are still running off the old web server. The DNS has been transferred, so when the blue message goes away you know you are on the new web server as well.
If you want to switch to using the new server without waiting for the DNS, you can add this line into your C:\windows\system32\drivers\etc\hosts file:
220.127.116.11 www.howtogeek.com blogs.howtogeek.com howtogeek.com
Otherwise you can just wait for the DNS to update... it's not a big deal either way. The articles will still load off the old or new server, no changes have been posted there.
So from anybody's perspective that is reading this, just use the site as you normally would, except perhaps it'll be a little slow for a few hours.
