RH 11 to Technical Comm Suite Conversion?

I'm going to make a whole bunch of people jealous here, but here goes...

I landed my dream job as a full-time permanent tech writer with a software company of 47 employees and started last week.  They had a programmer who doubled as a tech writer and did all of his authoring directly in RoboHelp 8.  I'm the only tech writer for this company now, as this other programmer is needed to do programming full-time.

Since we have a major release and update of all of our products coming up in December of this year, I asked my manager if we could upgrade to RoboHelp 11.  He not only is willing to do that, but for the little bit more money, he wants us to get Technical Communication Suite 5 so that I can also be the sole instructional designer using Captivate and the sole webinar teacher using Presenter.  Yay, job security!  Maybe I can go for a whole year without getting laid off

Here's my question - Should I continue to author in RH11, or is it possible to "back author" the soon-to-be-old content from RH11 to Frame 12?  I've had wonderful experiences in the past using Frame to RH, but I've never done it the other way around.  My manager does want print documentation, and he does want content to be mobile device friendly in the future, but not for the December release.

Would it be worth it to put all of that content in Frame 12 now so that in time to come it will be easier to update for smaller releases?  We have one big release a year, and smaller ones at other times during the year when needed.

Thank you!
