Thank you Moosa,
I just took a look at where www.technews.com links to and that gave me the vastly more insight to what they are trying to accomplish and makes me believe that they will survive without the tech section
unfortunately, the non-www.version takes you to a dead page.
I would not worry too much about losing page rank based on the site it links to most likely being the new site you are speaking of I doubt this is a secret because you showed us the domain that points to it. of course I will not put that URL on here out of respect for you but I have placed the URL you mentioned above so people will know what you are referring to.
However, if you are going to go through with this I would place quality content on technews.com and take away the 301 redirect that points back to the main news site
I would then do something similar to what Moz did when they moved from SEOmoz.org to Moz.com they made http://moz.com/rand/ a live site that contained high-quality unique content in order to warm up the audience to the domain as well as Google
only if you are going to splice these things into two different sites would I go ahead and move your technology information over to technews.com domain and place all that content on it.
I would also want to inform your current readers of exactly what is going to occur.
In less you are going to really start going crazy on technology and have an entire business plan based around it which I am pretty sure you do if you are planning on doing this.
Then I would move forward with changing the tech section of your current site to become the beginning of technews.com ( I have made this a live link to where the www. version of it links so people can be of better help by under understanding the scale of this change.)
Unfortunately, any traffic, links, social media approvals, page rank and everything that is currently helping you rank with your news technology section will disappear. as soon as Google crawls the site and notices the 301 redirects.
Because you are not changing domains like when SEOmoz.org became Moz.com it is very unique that this type of thing occurs. Though I can understand now why you would want to do it.
I would recommend taking a tool like http://deepcrawl.co.uk/ and having it run a universal index on your current news site the reason I recommend Deep Crawl is I have used it with great success on extremely large sites over 1 million URI's it has the ability to scale Because it is not based on how much your local workstation or desktop has for RAM I believe it is hosted on AWS regardless because it is hosted it allows it to process the data on huge sites I usedit on the one Fortune 500 that I cannot name however it did a fantastic job.
if you read the information on this site you will see just how capable and indispensable tool like this is when making changes to a site a as large as your news site
http://deepcrawl.co.uk/features/advanced-processing
Another tool you should not be without my opinion is Screaming Frog SEO Spider though for the amount of pages that you will need to crawl you will need a workstation with a lot of RAM as it does many of the same things deep crawl does however requires you to install it on your local workstation or desktop it can be installed on Mac, PC and Linux though I have placed it on a Verizon Terremark server running Ubuntu with 24 gigs of RAM with a lot of success there are other things you will want it around for checking. I would purchase the Pro version Of

I would then use a combination of Moz http://moz.com/researchtools/ose , https://ahrefs.com/ , http://www.majesticseo.com/ & Google Webmaster tools or www.google.com/webmasters/ to look at the back links pointing to technology.

I would follow the directions that are laid out in the URLs below because making a mistake when doing this will be costly to your new satellite business.
Hosting your new site on a server that you trust to have the capability to host it protect it is paramount to it surviving
Peek Hosting http://www.peakhosting.com/
Terremark http://www.terremark.com/
FireHost http://www.firehost.com/
To gain speed and reliability I would recommend not using the current DNS setup
ns-1027.awsdns-00.org
pdns6.ultradns.co.uk
simply because AWS route 53 or ns-1027.awsdns-00.org depends on both DynECT Dyn.com & UltraDNS http://www.neustar.biz/services/dns-services is to keep itself alive and meaning if in the extremely unlikely instance of both of them going down you are out of luck.
However, your current setup depends on a secondary DNS that depends on your primary DNS being up I hope that makes sense.
I would simply do what many other companies that do not want down time and need very fast name servers do use DynECT along with UltraDNS or combine DynECT with EdgeCast Route DNS
Amazon.com is not backed up by AWS Route 53 as you can see below it is a combination of DynECT & UltraDNS two keep your site from having issues so it is not a good
use
ns1.p1.dynect.net & ns1.edgecastdns.net
or
ns1.p1.dynect.net & pdns1.ultradns.net
or just ns1.p1.dynect.net
UltraDNS had a bout of downtime less than a month ago on salesforce
Dyn has never been down ever look At the Way, Amazon configures their server DNS.
