    Hi guys,

    Wondering if anybody could help me. I currently have a physical server running 2008 r2 Enterprise running the following roles (screenshot attached)

    and I'm trying to upgrade to Server 2012 (I've tried both Standard and Datacenter) yet I receive the attached error when I enter the product key (Which is pretty much the first stage you have to take)
    error.jpg

    Both are genuine ISO's and Keys from my university DreamSpark Premium account. Now I've tried inputting the product key into a virtual machine running the same iso just to check and the key passes (I didn't continue on to install the server, didn't want to risk using up my key if that's possible).

    Any assistance would be greatly appreciated, and if you need any more information please let me know.

    Thanks in advance,

    Cal.

    Never heard about server OS upgrade, this is not a consumer OS, even if possible I will not recomend it.

    Thanks for the reply,

    The Server upgrade path is fully supported, as per technet article: technet.microsoft.com/library/jj134246.aspx

    I just don't understand why it's telling me the product key doesn't match the image..

    This is very interesting, I am running the network in server 2008 R2 as well, I hope I don't have to deal with this issues when I start upgrading by the end of the year.

    for those roles, you sOOOO do not need datacenter... Datacenter is for like 64+ cores and gigabytes upon gigabytes of ram. Also, while an in-place upgrade of Server 2008 r2 is supported, as someone mentioned, it is not advisable. you should always do a fresh install of a server OS.

    Thanks for the reply, I'm using datacenter because it was the first one I clicked on Dreamspark when I first started to use it, I didn't know much about the difference back then, also you're allowed unlimited virtual licenses I believe and I'm forever adding Virtual servers to play around with.

    Whilst I know it's not advisable I would really prefer to do an inplace upgrade instead of having to rebuild my entire domain, if anybody could help me with this I would be very grateful. If it comes down to it though, is there any way to backup my users, their data and things such as Group Policy?

    Thanks again,

    Cal

    It doesn't matter, 2012 Standard and Datacenter are exactly the same. The only difference is in virtualization rights.

    Not sure how but it's working now, perhaps Microsoft made a change as it downloads around 500kb if you select get the latest setup

    Upgrade has gone smoothly with no issues so far. Loving server 2012 and now moved to Hyper-V instead of VMWare and VirtualBox.. props to M$ on this one

    Yes, I just upgraded one of my physical DataCenter machines this past week.
