BIOS to UEFI no backup restore possible? RRS feed

  • Question

  • We have a DELL R510 server with Windows SBS 2011 (Data, Exchange, ...), we running out of space on the server. We currently have this configuration:

    • 2x 300GB SAS in RAID 1
    • 2x 2TB SATA in RAID 1

    We want to add 4x 4TB SAS in RAID 10. To be able to read the new hard drive we need to change the server boot option from BIOS to UEFI.

    My question is: Can I backup the server (bare metal with windows backup), change from BIOS to UEFI and restore the backup, without reinstalling ? If not, how can I proceed (convert MBR to GPT) ?

  • No. You cannot restore BIOS firmware backup on to a fresh install on UEFI. GPT/MBR is not the issue. It's a different firmware. Among other things, you will get "inaccessible boot device" blue screen. You will need to backup, do a fresh install on UEFI, install and configure all apps, and restore data.

    This is quite difficult depending on how many apps you have and how adequate is their documentation and support.

    And it will incur significant down time.

    This is precisely why virtualization is the best thing that ever happened since man learned to walk erect.

    If this was a Virtual Machine, you would live-migrate it, wipe and reinstall your disks on the host with new UEFI, enable Hyper-V role, join the domain on the host, live-migrate the VM back. Piece of cake! simple, easy, predictable time/cost, and NO down time. 

    Having said that, there are 3rd party tools that do P2V (Physical to Virtual) conversion, even with no down time, like Platespin - now owned by NetIQ. You can use it to virtualize this server, do your hardware rebulild, and get the server - now a VM back on the updated hardware.

  • hi

    If this is your only server and you running SBS with exchange you might run into a problem. Single point of failure.

    Perhaps you should introduce temporary hardware, setup another exchange and DC, let it replicate, create a DAG and then do what you need to do. Raid 10 is a bit high, why dont you look at Raid 5?

  • Hi,

    I know that we have a single point of failure. The company asked me to move from cloud base email to on-premises Exchange.... not my decision/recommendation.

    Can we create a DAG with SBS 2011, I thought it was only with Exchange Standard not with SBS ?

    RAID 10: It's just to maximize the performance but maybe RAID 5 is enough.

    Thanks,
