Migrating a section to a new domain

I have www.SiteA.com which contains a number of sections of content, a section of which (i.e. www.SiteA.com/sectionA), we would like to move to a new domain www.SiteB.com

Definitely we will ensure that a redirect strategy is in place and that we submit a sitemap for SiteB

Two Questions

1. Since we are only moving part of SiteA to SiteB, is there another way of telling Google that we changed address for that section or are the 301s enough?

2. Currently, Section A  (under SiteA) contains a subsection where we were posting an article a day. In the new site (SiteB), we decided to drop this subsection and write content (but not "exactly" the same content) under a new section. During migration, how should we handle the subsection that we have decided to stop writing?

Should we:

A. Import the content into SiteB and call it archives and then redirect all the urls from subsection under SiteA to the archives under SiteB?

OR

B. Do not move the content but redirect all the pages (365 in total) to where we think the user would be more interested in going to on SiteB?

Note: A colleague of mine is worried that since the subsection has good content he thinks its necessary to actually move the content to SiteB. But again, looking at the views for the archives it caters for 1% of the the total views of this section. In other words, people only view the article on the day it is written.

I hope I was clear :)

Your help is appreciated

Thank you
