Site changes lead to big questions

[sdennison]

I'm making some changes to my business that will cause me to move my blog to a new domain. The existing site will serve as a sales campaign for our full service programs and I want to keep visitors focused on that campaign. The old site will serve much like a mini site with a sales letter and video sales letter.

In moving the blog content to another page - I found a post from Rand from a few years ago http://www.seomoz.org/blog/expectations-and-best-practices-for-moving-to-or-launching-a-new-domain.

The way I wanted to approach this was to remove the content from the old site, and then resubmit the site map to Google for indexing. Of course they'll notice that the blog pages are gone. (probably a load of 404's)

After perhaps a week, I'd repost the content (about 50 posts) on the new domain, which will be little more than a blog.

I'd like some input on the way to approach this. Should I...

a) Follow Rand's formula?

b) Go with my idea (sort of the brute force model)?

c) Consider an alternative method?

It's probably worth mentioning that none of these posts have high search engine rankings.

I appreciate your input Mozzers!

I read back over what Rand posted over 5 years ago!  I have moved several sites and what Rand said is still best practice.  Google indexing is nothing to play with.  Taking down content and then trying to get it to rank again can look very spammy to Google.
