I have a Dell PE T110 Server running Windows 2008 which has a mirrored RAID 1 system with 2 500GB hard drives. The drives are at about 88% capacity and need to migrated to larger drives. I'm looking for best option to migrate to larger drives. The RAID is hardware RAID and in Windows its partitioned into C: and D: drives.
First, option I was thinking of was to use a hard drive copier I have to copy each drive to a larger drive and then expand in Windows. I've done this plenty of times on a single drive desktops, but, never tried this with RAID drives and I'm not sure if this will corrupt the RAID since the drives will be different from the original drives.
2nd option I was thinking about was to just image the system to an image file, put in the new drives, build the RAID in the controller, and then, restore the image to the new drives. My concern with this option is the amount of time it would take. The drive to be imaged contains about 430GB.
Any suggestions would be appreciated.
