Windows 2008 Vs 2008 R2 application support

IBM Systems director 6.1.2 is supported on 2008 x64, but it hasn't been tested on R2 and so is not technically supported.  i need to rebuild this server and for other reasons it should be R2.  The question is are the kernels, or security models etc, that different to be concerned, or is it a formality for the most part?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

They are quite similar but have some differences. The comparison is like Vista to Windows 7. Most apps will be cross compatible but the odd one may have issues. I do not know if IBM Systems director is R2 Compatible but I have had very few issues between the two.

The Director version I will be installing is technically not tested/supported on R2, but it works fine on 2008.  i'll upgrade in a  couple months to a new version that will be supported on R2.  i figure I don't have much to lose in this particulr situation.  

Thanks for the feedback!
Yeah, sometimes just testing it is the best way to go.
