I create an image of my RAID 0 daily using
Drive Image. I have not had to restore from that image, although my research on it indicates that it should work. The Drive Image disk is bootable and prompts for third party drivers same as an XP disk so I believe it will work.
I've got to believe that if I can image from the array that I can restore to the array.
Wish I could give you a definitive answer.
By hardware, I assume a different RAID card? If so, you had better install that card first and get the drivers installed before you proceed. It will be difficult, if not impossible to boot off that "new" array when your OS does not fully support the card. I believe you may have other issues with this as well that I, myself cannot forsee. I would proceed with caution and cover yourself with backups of your data.
I don't understand this LAN situation either.
