Migrating from 2008 SP2 To 2012 R2

hello guys,
i am trying to migrate my old domain controller (2008 sp2) to a new one (2012r2) on new hardware, i did an acronis restore of my dc to make all in lab test. 
I have some problem of replication . here is the DCDIAG :

Can you help me ?

Hi,
share out the Sysvol directory. However,  it is recommended that you enable the system to share this directory.
For additional information about enabling the system to share this directory out on its own:      (http://support.microsoft.com/kb/257338/EN-US/)
To verify that the Sysvol directory is shared out, you can either open Windows Explorer, or  type
net share at a command prompt to see if the Sysvol share is showing.  By default, the Sysvol share is located in the following folder: %SystemRoot%\Sysvol\Sysvol.
It is also recommended that you check the File Replication Service log.  When replication has completed (with a domain with just one domain controller) the File Replication Service log reports the following event:
Event 13516: The File Replication Service has stopped preventing the computer from becoming a domain controller.
The system volume can take some time to initialize depending on the network.

  • Inter-site replication and KCC, when migrating from 2008 SP1 to 2012 R2

    Hello,
    We have a very simple AD infrastructure, two sites.  I have built out a 2012 R2 server, extended the AD schema and promoted it to a domain controller.  Reviewing the existing AD replication topology, we currently have a 2008 SP1 server as a DC
    designated as the source/destination for inter-site replication, which appears to have been decided by KCC.
    I will be decomming this 2008 SP1 server, having migrated off the FSMO roles to a few other DCs.
    Will KCC automatically know to adjust the replication topology when the 2008 SP1 DC is offline?  Should I demote it after migrating off the FSMO roles?
    Thanks,
    Matt

    Hi,
    Thanks for your post.
    By default, the KCC reviews and makes modifications to the Active Directory replication topology every 15 minutes to ensure propagation of data, either directly or transitively, by creating and deleting connection objects as needed. The KCC recognizes
    changes that occur in the environment and ensures that domain controllers are not orphaned in the replication topology.
    For more detail information, you could refer to:
    http://technet.microsoft.com/en-us/library/cc961781.aspx
    For the migration, you could transfer the Flexible Single Master Operations (FSMO) Role and remove the Windows 2008 R2 domain controller, please refer to:

  • File Server Migration from 2008 Standard to 2012 Standard accross different subnet

    Hi
    Im going to migrate File server from Windows 2008 Standard server to Windows 2012 Standard . Source and Destination Servers are on different subnets . According to this
    http://technet.microsoft.com/en-us/library/jj863566.aspx I cannot use Server migrations tool in-built into 2012 .  Im not sure if I can use file server migration toolkit 1.2?.  
    Also my Domain controllers are mixture of Windows 2003, 2008 , 2008 R2 and I've upgraded the schema level to 2012 R2 . Is there anything else I need to be aware of ?
    Can anyone please recommended best way to go about doing this migration . Is file server migration toolkit 1.2 is compatible ?  .
    Only reason I don't want to use Robocopy to this is because If I miss a small setting etc then I will face unwanted downtime.
    I presume Migration toolkit will also create all the Quotas etc on the destination server .
    Thanks
    mumtaz

    Hi mumtaz, 
    We could use file server migration toolkit 1.2 to migrate file server between the two subnets. In order to maintain security settings after the migration, please ensure the security of files and folders after they are migrated to a target file server, the File
    Server Migration Wizard applies permissions that are the same as or more restrictive than they were on the source files and folders, depending on the option you select.
    In the meantime, quota cannot migrate by this tool but we can export and import the quota using dirquota command. Export the templates as xml and then import to new server:
    dirquota template export /file:C:\test.xml
    dirquota template import /file:C:\test.xml
    For more detailed information, please see:

  • Domain Controller, DHCP, DNS Migration from 2008 r2 to 2012 Essentials

    I would like to migrate Domain Controller, DHCP, and DNS functions to a new 2012 Essentials server in a 2008 r2 domain.  I would like  the 2008 r2 server to remain as applications server.  Is it possible to do this?  I've seen in TechNet
    a reference to this type of migration, but am concerned about the reference that after 21 days the 2008 will shut down.  Is it that the server will shut down or the Domain Controller function on the 2008 will shut down? I will need the 2008 setup as is
    for our application server, so I want to be sure that the migration will not interfer with that.

    As long as your existing server is not also an SBS or other Essentials server, it'll be fine. The shutdown after 21 days occurs when multiple SBS or Essentials servers are on the same domain.

  • I did an Unsupported InPlace OS Upgrade from 2008-R2 to 2012-R2

    Well, I misunderstood what was supported and upgraded the OS on a SCCM 2012-R2 server from 2008-R2 to 2012-R2. (The one and only SCCM-server in the site)
    All seems to work well, my concern now is what can I expect of future problems? Should I do the backup-install-restore procedure now to be sure or let it run until... "maybe something" happens?
    Thanks.

    "not supported" just means that MS did not test that scenario (and it does not automatically mean that it does not work).
    I've done such an OS upgrade in my lab and were running into some smaller issues (MP/DP/SUP = the roles that require IIS) and were able to fix them by removing and re-adding those roles but YMMV.
    The supported way would be: recover from backup. But you can also have a close look at all roles and see if they are still working.

  • Certificate errors after upgrade from 2008 r2 to 2012 r2

    After upgrading a DC from 2008 R2 to 2012 R2, Outlook will no longer connect to outlook.office365.com.  This appears to be a direct result of the upgrade, worked before and failed after.
    I get a flurry of message boxes when I launch Outlook, and it will run but not connect.  No path through the messages (granting permission to ignore the error, or installing the certificate) makes any difference.  Not seeing anything in the event
    logs, and have no idea how to fix this.
    In addition, IE is now raising cert complaints on every site, doesn't matter which.  Firefox seems to be managing okay, for the most part.
    Thanks for any guidance.

    Hi Michael,
    I am so sorry for the delay.
    I was trying to find more useful information about this issue, though there are very little information other than installing the trusted root certificate which is provided by the KB
    article above.
    I would suggest you download a
    certificate chain and install it.  
    If this method still couldn’t help you solve this issue, since you are using third party certificate (VeriSign) for your organization, you can get more efficient support by contacting
    third party support services.

  • How do I migrate a FAX server from 2008 R2 to 2012 R2

    Hi- I have two DCs (one 2008 R2, one 2012 R2) I'm going to build a new DC with 2012 R2 and remove the 2008 R2. This server is hosting FAX services. How do I move it to the new server? Can only find articles talking about SBS and using a migration wizard...

  • Possible route from 2008 r2 to 2012 r2 Essential on different machines?

    I have a Windows server 2008 r2 standard on a machine and we bought a new server.
    I want to transfer all my users, groups, machines from the 2008 r2 machine to the new 2012 r2 Essential machine.
    I've read the Migrate from Previous Versions to Windows Server 2012 R2 Essentials and
    Migrate Windows Server 2012 Essentials to New Hardware article but I'm still not sure this can be working with the 2008 r2 standard too.
    If it doesn't work, restore a system state backup on 2012 r2 from 2008 r2 is possible? Or Is there a method to transfer my users and computers?
    Is it possible that after I demote the original server, I rename the new server to the name of the old server?
    I have an SQL server instance in the source server. This and the user profiles are the only things I want to transfer.
    Thank you!
    Tamas

    It is not as simple as that with an Essentials server as it also runs a certificate authority, and the Essentials features are heavily tied into that.

  • Deprecated Code - Migration from SQL 2005 to 2012

    Hi,
    We're planning to upgrade our database from SQL Server 2005 to 2012. Based on this
    link, it seems there's no code conversion needed in terms of Data Type, Keywords in creating SPs, Function, trigger.
    The only thing that concerns me is this
    Set options
    SET ROWCOUNT for INSERT, UPDATE, and DELETE statements
    TOP keyword
    SET ROWCOUNT
    109
    But other than that, it should be good.
    I would also like to get any feedback from other user who migrated their database from 2005 to 2012. What were the issues encountered during the process. Any tips and suggestion will be much appreciated.
    Many Thanks.

    What is your mode of upgrade
    1. In place
    2. Side by side
    You must also read

    If you are just using DB engine features and SSIS I would advise you to first run upgrade advisor and look for breaking changes or unsupported scenarios. make sure you mitigate all such issues.
    There is also a feature where you can side by side upgrade database by backup restore to SQL Server 2012 and still keep
    compatibility level to 90
    (but that is not advised)

  • Migration from 2008 Foundation to 2012R2 Std

    I have a client that needs to upgrade to Server 2012 R2 Std from Server 2008 Foundation. From what I gathered here on TechNet, the best way of doing this is to do the following in order:
    1) Setup new 2008 R2 server
    2) FSMO from 2008 foundation => the new 2008 R2 server.
    3) Demote 2008 foundation server.
    4) Upgrade the 2008 R2 server to 2012 R2 Std.
    Is this correct or do I need to do any other additional steps?
    (=Chris=)

    Hi Chris,
    Thanks for your question. However, I am not quite sure of your environment.
    Is the Windows server 2008 Foundation a DC with FSMO role? Is it the unique DC in the domain? Since you mentioned “Setup new 2008 R2 server”, did you mean that you have another server except
    the Foundation server? I would appreciate it if you can share more information about your existing environment.According
    to the steps that you have provided, it seems that you want to migrate your AD from server 2008 Foundation to Server 2012 R2 instead of upgrading the operating system to Server 2012 R2 standard.
    Windows server 2008 Foundation cannot upgrade to Windows server 2012 R2 directly, you need to upgrade it to Windows server 2008 R2 firstly. For general migration steps, you need to add the
    new server into the domain and make it to be a DC and Global Catalog server. Then transfer the FSMO role to the new server. After you make sure that the duplication between the DCs is competeled, you can demote the old DC. In addition, I recommend you
    to backup your old DC before migration.
    Best regards,
    Susie

  • Upgrading domain from 2008 R2 to 2012 R2

    I am looking to upgrade my domain from server 2008 R2 to 2012 R2.  We have 10 remote sites, each with a single physical ESXi host hosting 2 vms, 1 2008 R2 vm with the ADDS/DHCP/DNS/File Services (user home drives) roles and the second 2008 R2 vm
    runs WDS/MDT and a couple applications.  At our main site we have a physical 2008 R2 DC which holds all the FSMO roles, a vm with the ADDS/DHCP/DNS/File Services roles, and another vm running WDS/MDT.
    I've gathered from my research that Microsoft recommends clean installs when upgrading DCs but since our DCs are also file servers that's not an ideal course of action for us, it'd be a lot of additional steps.  My plan at this point
    is to bring up a new physical 2012 R2 server, make it a DC, transfer the FSMO roles to it, then demote and retire the current physical 2008 R2 server.  For the virtual DCs, since they are also file servers, I'm leaning towards in-place upgrades
    on them, unless anyone would advise against.
    The other thing I'm considering is creating a 2012 R2 DC at each remote site, then demoting the current 2008 R2 DC, leaving some combination of DHCP/File Services on it, then run an in-place on it to 2012 R2.  This would requre another Windows license
    though since our physical hosts are not on Hyper-v.
    For the virtual servers running WDS/MDT, I personally prefer an in-place so I don't have to move the MDT deployment share, but I'm open to suggestions. 
    What are your recommendations?  Which server should I upgrade first?  How much time should I allow between each DC upgrade?  I appreciate the help.

    As per recommendations, A DC should be solely utilized for AD/DNS/GC & if environment is small for DHCP. The problem in using DC for other purpose arise during upgrade scenario, when you have to demote the DC or performance. Demoting the DC is very simple,
    but if its running with additional role, it becomes challenging, if demotion has to be performed forcefully.
    Secondly, from the security point, its not a great idea to run DC with other roles esp file servers, if there is any infected file then the whole domain can be compromised or infected.
    What is more relevant in upgrade is testing the applications before you perform or upgrade the schema. If there is no issues then you can perform the upgrade based on your convenience. But necessary documentation & testing prior & post has to be
    followed.
    My personal recommendation would be upgrade the schema(surely test the schema upgrade in lab before you do in production), create a new server either VM or physical, configure it as an DC & transfer all FSMO role & slowly try to segregation between
    DC & non DC servers.
    Yes, i know it will cost additional licensing burden, but from the environment point of view it will provide you an ease of administration & troubleshooting.
