Desactivate and reinstall Photoshop cs6

Bonjour

I will have a new computer in a week

I have Photoshop cs6 extended on my actual computer

If i want to reinstall CS6 on my new computer must i deactivate it from my actual computer before the reinstallation ?

Someone have did it before ?

I also have cs3 design premium(still use illustrator from this suite) Must i do the same ?

Thanks
