I have purchased a new RAID controller and want to migrate from my existing controller without re-installing the OS. The RAID controller is mirroring the OS hard drive.
I talked to Adaptec and they told me that the only way was to re-install the operating system..."the RAID tables on the hard drive are incompatible". Is this the truth? Or, a quick/safe answer?
I have backup imaged the existing OS and replaced the controller and restored the image to the new array I created, but I was not able to access the OS because it didn't have drivers installed for the new controller (INACCESSIBLE_BOOT_DEVICE).
I plan on installing the drivers and trying to get both cards into the system at the same time, but I'm looking for someone that has done it and can speak from experience that it works and it isn't a waste of my time.
