Product activation & reinstallation

I currently have a system with Windows XP operating system and Office 2007
installed. I will be updating to Vista soon and will carry out a full
re-installation after a re-format of the HD.
Are there any issues with the activation of my copy of Office 2007? Do I
have to formally un-install it to allow the software to be re-activated?

Guidance please.

If you are 'upgrading' your current o/s, as apposed to clean installing
Vista, all your applications should remain intact.
