Best Pracice to Obsolete a Blog

[Bucky]

Hi,

I have a blog that has thousands of URL, the blog is a part of my site.

I would like to obsolete the blog, I think the best choices are

1. 404 Them:  Problem is a large number of 404's. I know this is Ok, but makes me hesitant.

2. meta tag no follow no index. This would be great, but the question is they are already indexed.

Thoughts?

Thanks

301 them to your homepage then

I am almost positive, that using a 301 to the main page would be considered a soft 404 error
