Migration from Server 2003 to Server 2012

    Question

  • hi guys, i have a windows 2003 R2 box (AD Domain Controller) and it has c and d drives.

    C drive where system is installed has this space:

    Whole C drive is 12GB
    Free Space is around 580MB

    I will just ask a general question, I know there's a lot of process and steps to be done.

    Assume, I know all the process and steps for the migration (just assuming hehehe).

    Question is, with the current free space and c drive capacity. Would that be enough for migration?

    and one more question, it's a Windows 2003 R2 box, I will be able to migrate it to which edition of Windows 2012? 

    Is it possible to migrate from Windows 2003 R2 to Windows 2012 Standard?

    Thanks for any input. :)

  • With that little space on the C drive definitely not. Just checked my 2012 AD & DNS lab machine, and the c:\windows\ folder alone takes up 16GB, without counting any of the other folders on c:\. Compare that to a 2003 box I've got with SQL 2000 installed on it, and the c:\windows\ folder is only 2.8GB.

    Additionally, as part of the upgrade process I believe it automatically makes a backup copy of the c:\windows folder so old settings can be recovered if required afterwards.

    In terms of upgrade path, is your 2003 R2 box 32 or 64 bit? If it's 32 bit then it's all a moot point as you can't upgrade from 32 to 64 bit, and since 2008 R2 there's been no 32 bit option available.

  • Hi Keith, thank you so much for your reply.

    It's a 2003 R2 Box 32bit (but HW supports 64 bit). 

    Is it possible to upgrade from Win 2003 R2 to Win 2012 Standard or either Win 2012 Essentials?

  • If it's a 32-bit install of Windows then the only option for an in-place upgrade would be server 2008 (not R2), there's no way to go from 32-bit to 64-bit OS (the HW support isn't relevant here). The only way to get 2012 on that box would be a fresh install.

    I can understand why, though as someone who has several 32-bit 2003 servers running currently I also find it annoying.

    Your best option realistically is to build a new 2012 box, get it on the existing domain, move things like the global catalog to the new DC, demote the 2003 box, and finally disjoin the 2003 box from the domain. There's a good guide to the process and the roles which need to be moved (before demoting the 2003 box) here http://blogs.technet.com/b/canitpro/archive/2013/05/27/step-by-step-active-directory-migration-from-windows-server-2003-to-windows-server-2012.aspx
