The best way is to make operations offline, i.e. take HDD from PC and clone it in other PC, then return new HDD back. BTW, you need to use a sector-level (low-level) cloning tool, cause Intel RST configuration is stored in hideen area of HDD, and partition-level tools will be unable to clone it.
It is necessary to keep using the same BIOS configuration and RST settings.
If you are using only 1 Hard Disk Drive (RAID ready), Intel recommends to disable acceleration, create a backup of your information and install the operating system and drivers on the new Hard Disk Drive from scratch.
