Upgrade of Windows NT 4 SP6a PDC

By jmcnally ·
I have a PDC with Windows NT 4.0 SP 6a as NOS. The machine is a clone Server with a Hardware Mirror and Stripe Set with Parity for fault tolerance.
I have ran the checkupgradeonly utility for Windows 2000 and have no problems for the upgrade butI am concerned with the upgrade on the raid 1 and raid 5 issue.
I want to be in the safe side and wonder if there is anything that I should do prior to upgrading the machine to Windows 2000.
I read that if there is a mirror set it must be broken first (do this apply to a hardware raid?)

Upgrade of Windows NT 4 SP6a PDC

The mirror set does not have to be broken first. The mirror set will be "upgraded" to Win2K but as a sort of "legacy" mirror set in the NT4.0 mode. The disks will not be dynamic disks, as they are in Win2K mirror sets, so you won't be able to manipulate the volumes the way you can on Win2K disks. Other than that, it doesn't make much difference. However, if you DO later want to change anything, you will have to break the mirror, upgrade each disk from basic to dynamic, and then recreate themirror. I'm not 100% sure about the striped set with parity (assuming this is software RAID not hardware). Hardware RAID wouldn't be affected. I don't believe there is any significant difference between Win2K software RAID and NT4, so I don't think you should have a problem. Hope this helps!
