In Place Upgrade WSUS windows 2008 R2 into windows server 2012

Hi Team,
i had question. I have windows server 2008 R2 and installed WSUS role at that server.
Can I do inplace upgrade into windows server 2012 std edition?
is there any impact into wsus services?
thanks

If it is not a DC, upgrade should be easy. And there shouldn’t be any problems.
The question was about upgrading a WSUS server, and regardless of whether it's a DC or not, it most emphatically will not be problem free. In fact, it's flat out not possible! On WS2012 the upgrade will be blocked if WSUS v3 is present,
and on WS2012R2 it will corrupt the WSUS installation beyond repair requiring a reinstallation of the operating system.
Please review the
WSUS v6 documentation regarding upgrade requirements.
Warning
Upgrade from any version of Windows Server that supports WSUS 3.2 to Windows Server® 2012 R2 requires that you first uninstall WSUS 3.2.
In Windows Server 2012, upgrading from any version of Windows Server with WSUS 3.2 installed is blocked during the installation process if WSUS 3.2 is detected, and you are prompted to first uninstall Windows Server Update Services prior to upgrading Windows
Server 2012.
However, because of changes in Windows Server 2012 R2, when upgrading from any version of Windows Server and WSUS 3.2 to Windows Server 2012 R2, the installation is not blocked. Failure to uninstall WSUS 3.2 prior to performing a Windows Server 2012 R2 upgrade
will cause the post installation tasks for WSUS in Windows Server 2012 R2 to fail. In this case, the only known corrective measure is to format the hard drive and reinstall Windows Server 2012 R2.

  • SCSM 2012 R2 - In-Place Upgrade to Windows Server 2012 R2

    Hello,
    is an in-place upgrade of the underlying OS from Windows Server 2012 to Windows Server 2012 R2 supported by SCSM 2012R2. I know of some products where it is supported, some where it isn't (e.g. Exchange) but I haven't found any information on SCSM (Management,
    DW, SQL, DWSQL).
    Thank you in advance.
    Regards
    Sascha

    i would never recommend upgrading the OS on any production environment, especially you have any virtualization and can stand up the new OS on the same hardware. 
    that being said, i don't see any obvious reason this would fail, but i don't thing it would be obviously supported either. 

  • In-place upgrade of Windows Server 2012 RDS to R2 fails

    Hi All
    I have a Server 2012 Standard RDS virtual machine (vmware) on which I have tried doing an in-place upgrade to 2012 R2 but it constantly fails.
    It sits at the "Collecting files, settings and applications" process for quite a while - always on 0% and then says: Installing Windows was Canceled "Setup can't continue. Restart the computer and restart Setup. When prompted, try getting
    the latest updates."
    I have tried combinations of all the settings during setup to look for updates, not look for updates, etc., rebooted several times, even disabled the RDS services and still the same result.
    As a test, I tried doing an in-place upgrade on the base OS installation that was used to create this VM and it works perfectly. The only difference between the servers is that the live has RDS role installed.
    Is there any Microsoft documentation on the 2012 RDS in-place upgrade process to R2?
    Can anyone offer any suggestion as to why the in-place upgrade might be failing with the RDS role installed?
    Thanks heaps

    As I stated I have already tried an in-place upgrade on the base 2012 vm that I used to create the production RDP server and it worked.
    It seems that the RDS role may be preventing the upgrade?
    Ideally I want to go down the in-place upgrade on the production server as we have alot of users using this machine. I would rather not have to build an R2 RDS server from scratch.
    if you really think the RDS is preventing the upgrade, how about stopping the RDS service then do an in place upgrade.
    check how it goes.. :)

  • Upgrade from Windows Server 2012 Active Directory to Windows Server 2012 R2 Active Directory

    We are currently running Windows Server 2012 Active Directory and would like to upgrade to Windows Server 2012 R2 AD. Is it OK to just do an in-place upgrade, or is it advisable to build new domain controllers on R2? Are there any guides or articles anyone
    can recommend?

    To upgrade DC(Domain Controller) from windows server 2012 to windows server 2012 r2, please refer to these articles:

    IPAM Upgrade Failed - Windows Server 2012 R2
    Hi All,
    I'm experiencing some problems with the upgrade procedure of an IPAM service hosted on a Windows Server 2012 R2 instance which originally was deployed on a non-R2 version. I've recently done in-place upgrade of the W2K12 OS to W2K12R2 which went absolutely
    fine, however when I'm trying to upgrade the IPAM service itself (from v6.2.0.1 to v6.3.0.1), I'm receiving an error message right after the database schema update procedure.
    Received error message:
    Failed to convert Schema. Please see the details.
    The given key was not present in the dictionary.
    Please restart the Wizard to update the IPAM server.
    Tried to restart the wizard several times, but it ends up with the same result.
    Also I noticed that the event log shows some authentication problems with the WID DB service:
    Connecting to IPAM database failed with,
        Number: 18456
        ErrorCode: -2146232060
        Level: 14
        State: 1
        Message: Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.

        Database Path: C:\Windows\System32\ipam\Database
        Database Server:
        Database Server Port: 0
        Username:
    The original IPAM deployment was pretty much a standard one by the official MS guides so there were no custom actions applied at any point in time. Right now I can access neither the IPAM features nor the previously made inventory, because server manager wouldn't
    let me do so until the upgrade is complete. For the time being this upgrade failure seems to be a bug.
    Kindly ask you to help me out with this issue.
    Thanks in advance.

  • Windows Server 2012 Essentials upgrade to Windows Server 2012 Standard

    I've just upgraded a Windows Server 2012 Essentials to Standard via the Powershell command. The server restarted and is now Standard version. However I've noticed in the services that one particular service fails. 
    silsvc <Failed to Read Description. Error Code: 2 > 
    C:\Windows\system32\silsvc.exe
    It is set to automatic.
    I guess this is part of the essentials license and hasn't been removed. I would like to keep the Essentials Features however on a VM I replicated the same problem but when I removed Essentials features this service also got removed.
    Is it ok to just disable this service? because I want to keep the Essentials features. Is it going to cause any issues?

    Hello,
    What is the procedure to migrate to standard essentials without losing programs?
    Can you help me?
    actually I have windows server 2012 essentials and I want to upgrade to standard

  • Problems PXE booting Gen 2 Virtual Machines after Upgrading to Windows Server 2012 R2

    My Current Setup: 
    I have two virtual machines set up with Hyper V on my Windows Server 2012 Server.
    VM1: Configured to boot from an ISO file and runs Clonezilla server. 
    VM2: Configured to PXE boot using a legacy network adapter, and with a passthrough 250Gb hard disk. 
    These two VMs are connected to an external Virtual Switch, which allows physical machines to PXE boot to the Clonezilla server. 
    For the past few months I have been using this setup for two purposes:
    1. To clone physical machines to the Clonezilla virtual server (as a backup).
    2. To restore those image to the second VM if I find that need to get access to the files on the original image.. 
    This has worked perfectly, except for the fact that the speed of the legacy network adapter on the second VM (which is required to PXE boot) is very slow. But I know this is because of the limitations in how the legacy adapter works... 
    Now my problem:
    I found out that Gen 2 VMs allow you to PXE boot without having use a legacy network adapter, allowing me to image back to the VM faster. So I upgraded the Server to Server 2012 R2 . I then created the same two virtual machines on the R2 server. I can still
    PXE boot the Gen 1 VM to the Clonezilla Server but I cannot get the Gen 2 VMs to PXE boot properly. They get an IP address from the Clonezilla Server but then just stop with the following screen. (note: I have disabled the Secure Boot). 
    Are Gen 2 VMs unable to pull down images from anything other than a WDS Server? 

    Hi J,
    >>Unfortunately WDS is not a solution for us as it is dependent on the PC being part of a domain
    If you would like to make the client not join to the domain, please check the box before “Do not join the client to a domain after an installation.”  In addition, make sure not to set the client to the domain in the unattend file and do not prestage
    the computer in AD. "

  • BSOD after an in-place upgrade from Windows Server 2003 R2 to Window Server 2008

    Xylems92 wrote:Unfortunately, we cannot take this approach.We have to move to 2008 (not R2) due to a software that runs on this machine and is validated will not run on 2008 R2 and above. In order to keep validation, we can only do an inplace upgrade. If we choose to either purchase the software upgrade or revalidate the system, both approaches will cost $80k+. So i need this to work as an in place upgrade to 2008I feel your pain, but any company worth their salt will (meaning the vendor) should know that you cannot simply perform an in-place upgrade of a Server OS.
    Really the proper method is to backup everything, format and install Server 2008 (are you limited to 32-bit?), restore data/reinstall software. What's the reasoning for the upgrade? 2003 EOL or something else?
    Do you have a guarantee that the software will even work on...

    Hello everyone. 
    We seem to be having an issue when doing an in place upgrade on our windows 2003 R2 server to go to Windows 2008. Every time we try and do the upgrade, once the server reboots it blue screens with no real information. Just mentioned to try and do a check disk to check for hard drive issues.
    It gives us the option to go the earlier version of windows (back to 2003 R2) but nothing we have tried has succeeded so far.
    Does anyone have any suggestions?

  • Windows small business 2011 standard cannot be upgraded to windows server 2012 R2 Standard

    Can Sbs 2011 r2 standard upgrade to 2012 r2 standard?

    Hi,
    I agree with Cliff. There is no in-place upgrade and we have to do a migration.

  • Upgrading to Windows Server 2012 R2 from Server 2003

    If they plan to buy new hardware, then yes, this could be a great opportunity for you to learn and tinker with the new server without affecting the main production server. You can install Hyper-V, create some VMs, and learn what the different server roles do. Then perform the final migration when you're ready.
    There's tons of topics in the form and on Microsoft TechNet that'll walk you through, step-by-step, on migrating just about anything from 2003 to 2012. 
    I would of discouraged you if it was an in-place upgrade. If you're getting new hardware, take this as an excellent opportunity to educate yourself and don't feel afraid to reach out.

    Hi everyone! I'm relatively new to IT (I've only been working in a business environment for one year) and have already been tasked to build a new server for the company. Whoever built the current server configuration did a terrible job by "best practice" standards and the company wants to do a complete rebuild from the ground up. I have little experience in servers and feel I may be in over my head. At the same time this may be a perfect opportunity to test my skills and prove my worth.
    Do you have any tips/advice for setting up a new server (AD domain controller/file server/print server) while the server to be replaced is still running?

  • In-place upgrade from windows 2008 R2 to windows 2012

    Hi all,
    we are currently running SAP ERP EHP7 (Netweaver 7.40 ) on Windows 2008 R2 server, MS SQL 2012 database.
    Is it possible to do in-place upgrade to Windows Server 2012?
    We want to do upgrade without buying new hardware  and perform system copy.
    Regards

    Hi,
    the only note where we discussed our findings about in-place upgrades of the Windows operating system is SAP Note 1494740.
    Even though the upgrade to Windows Server 2012 is not discussed explicitly, the note is also valid for Windows Server 2012.
    The only thing you have to take care is: upgrade your system components (database, other 3rd party software) to versions supported on Windows Server 2012 before you are performing the in-place upgrade.
    Regards

  • Upgrade from Windows Server 2008 R2 SP1 to Windows Server 2012 R2

    Hi, I was trying to setup a new DC for our company, originally it's DC is Windows Server 2003 SP2, we decided not tomigrate it and instead build a new one from scratch which is Windows Server 2008 R2 SP1. I was able to set it up, perform windows updates,
    added roles, perform Domains and Trusts, etc
    When suddenly our global standards shifted to Windows Server 2012 R2, so instead of creating another server from scratch, this is the time to upgrade from 2k8 to 2K12 R2, besides the MAPtool which I've downloaded to check for prerequisites, etc, are there
    other things I need to be aware of? backups? etc.

  • Upgrade Windows Server 2012 to Windows Server 2012 R2 in-place upgrade

    I have tried to do an in place upgrade for Windows Server 2012 Standard to Windows Server 2012 R2 using the in-place upgrade at least a dozen times. Always with the same unhelpful failure message. 
    I have tried downloading the latest (setup) update and not downloading it - makes no difference - same error.
    I would really rather upgrade this server than re-install. I have scoured the internet looking for answers and I can't find anything useful. 
    I have downloaded the latest 2012 R2 Standard iso. The version of 2012 installed is a stock retail Standard version it was never an eval version.
    Any help much appreciated.

    I did check the article. I did the ADPREP as described and adprep worked fine. Unfortunately it did not make any difference. Log entries below:

  • Upgrading Windows Server 2012 Essential Eval to Windows Server 2012 R2 Retail

    I need to upgrade from Windows Server 2012 Essential Eval version to Windows Server 2012 R2 Retail.  What would be the easiest way to upgrade if license $$ is not an issue? The Server is a DC.  Would the following works:
    1. Upgrade from Windows Server 2012 Essential Eval to Windows Server 2012 Essential Retail
    2. Do a conversion from Windows Server 2012 Essential Retail to Windows Server 2012 Standard Retail (I suppose this just require several command line to enable the 2012 Standard)
    3. Do an in-place upgrade from Windows Server 2012 Standard to Windows Server 2012 R2 Standard (there is no need to do migration, am I right?)
    Thanks.

    I just did a simulation using Hyper V.  It seems that I'm able to do the upgrade sequence as described but I'm not sure whether there are any side effect that not yet surface out.  Here is the details steps that I took:
    1. Under Windows Server 2012 Essential Eval
    convert the Windows Server Essential 2012 Eval to Windows Server Standard 2012 using the following command in an elevated command prompot
    dism /online /set-edition:ServerStandard /productkey:xxxxx-xxxxx-xxxxx-xxxxx-xxxxx /accepteula
    press "y" and return to restart as prompted
    the productkey could be retail key or the KMS client keys (just for installation not for activiation)
    2. After reboot, the system become Windows Server 2012 Standard
    using admin account to login
    add admin account to the Enterprise Admins group and Schema Admins group if not already done so, logout and login again
    mount the Windows Server 2012 R2 Standard disk in, say, drive d:
    in an elevated command prompt, go the following:
    cd d:\support\adprep
    .\adprep.exe /forestprep
    .\adprep.exe /domainprep
    double click on d: in explore to run the Windows Server 2012 R2 Standard setup
    follow the instruction to complete the in-place upgrade from Windos Server 2012 to Windows Server 2012 R2
    3. After reboot into Windows Server 2012 R2 Standard, go to the charms bar, select setting -> server info, it will mention the server is not activated, click on Activate Windows and key in the Windows Server 2012 R2 Standard retail key
