Install on New System?

[Mad Dog 7.62]

So I have ordered a new system that will run DCS (and everything else) much better. My 1GB video card was just not hacking it in DCS 2.0.

 

Is there anything I need to do to the current system before I download 2.0, NTTR, and all my other modules on the new one? Do they need to be "deactivated" on the old one? I will be doing a reformat on the old system and either giving it my son or keeping if for a spare, I won't be running DCS on both. TIA!
