RAID 5

I am going to upgrade my NT PDC to Windows 2000 server DC with AD. This box is a Compaq machine and holds hardware RAID 5. I was wondering whether I need to break the RAID before upgrading and how can I go it? Even if I don’t have to worry about it for my upgrading process, it will always be helpful if I can get some tips on How to break hardware RAID.

Thanks
