Moving Entire Domain to New Site with New File Extensions

[dhidalgo1]

I have been looking for a while for a good an clear Step by Step guide for moving a site from an old to a new domain... so I guess a good discussion here, could help many web masters have a smooth transition.

So in your opinion, beside the obvious, what are the most important steps you must take?

Here is what I do:

1. 301 old site to new one and TEST.
2. Check Internal Links - Double Check for 404's.
3. Update your Social Profiles with new URL.
4. Let GWT and BWT of the change and request a Crawl.
5. Contact as Many of Webmaster as you possibly can to point your links to your new domain.

What's missing? What have you found helpful and/or Effective?

Danny Dover wrote this guide to moving domains back in 2009, but I did a quick review of it and it still looks good today.
