Upgrading hyper-v 2008 r2 to 2012?

is it possible/will it be possible to just upgrade hyper-v server from 2008 r2 to 2012 or will I have to reinstall the whole os and vms?

"Hyper-V Server (Server Core) cannot be upgraded to Hyper-V Server 2012. You can choose to install
a new copy of Hyper-V Server 2012 instead, but this is different from an upgrade, and does not keep your files, settings, and programs."
Any know how to work around this problem?
Yes - export your VM's and re-install your host OS! It really doesn't add that much time.
And here's a tip for quicker exports - if you have a VM that has several really large VHD's you can temporarily remove the VHD's from the guest VM config and then export. I had an SBS 2011 VM with the Guest OS, Exchange, Swap and User data all on separate
VHD's.
I shut down the VM normally and then detached the large user data VHD's. The export/import of the VM went much faster. Once the Host OS was re-installed and the VM was re-imported, I just re-attched the user data VHD's before restarting the VM
and the server in the VM was none the wiser. I went through the trouble of keeping the VHDs in same location in the virtual SCSI controller in the guest VM configuration settings, but I don't know if that's strictly required or not. It worked like
a champ and didn't add that much time to the overall process of rebuilding the HyperV host OS. If I ever get comfortable enough to switch to Server 2012 HyperV, I'll do the exact same process. For something as simple as a hypervisor OS install,
upgrading it doesn't make much sense to me! As others have pointed out you are MUCH better off doing a clean install. Especially if it won't upgrade it for you :o)

Upgrade Hyper Server 2008 to 2012R2

Hi,
I'm a bit confused if it is possible to upgrade Windows Server 2008 Standard SP2 and the Hyper-V Role enabled to Windows Server 2012R2. This page says NO:
http://technet.microsoft.com/en-us/library/dn303416.aspx
But in
this topic I read that it should be possible, but only when the Hyper-V Role is enabled.

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.

Hi,
For licensing related issue, you’d better contact Microsoft licensing team. In the United States and Canada, you
may call the licensing team directly at 1-800-426-9400
(select option 4), Monday through Friday, 6:00 A.M. to 5:30 P.M. (PST) to speak directly to a Microsoft licensing specialist. In this way, you will know the detailed information about license.
Worldwide customers can use the Guide to Worldwide Microsoft Licensing Sites http://www.microsoft.com/licensing/worldwide.aspx

In Place Upgrade RDS sever 2008 R2 to 2012 R2

Hi
I have a single RDS server 2008 R2 running the roles of RDGM, RDLM, RDSHC, RDWAC an Remoteapp manager. I want to do a in place upgrade to Server 2012 R2. Is this a supported path? Are there any step by step guides available?
Thanks
Gus

Hi Gus,
Sorry for the delay.
As TP suggested. Only RDG and RDL are supported for upgrading or migration. Other role are supported or upgrading or migration due to architecture changed.
Regarding the guide for setting up RDS 2012, please refer to the following:

VM Migration from Hyper-V 2008 R2 to 2012 successful but leave duplicate source VM with "Incomplete VM Configuration"

We are in the process of moving VMs from our legacy 2008R2 Hyper-V cluster to our new Hyper-V 2012 cluster using VMM 2012 SP1 CU3. Most VM migrations go just as expected and are completely successful. I have had a couple of VMs however that appear to successfully
migrate but leave behind the VM on the source 2008R2 in the VMM configuration with a status of "Incomplete VM Configuration." Using the VMM shell, I get the following:
Get-SCVirtualMachine | where { $_.Name -EQ "<VM>"} | fl name, status, VMId
Name : <VM>
Status : IncompleteVMConfig
VMId : <DuplicateID>
Name : <VM>
Status : Running
VMId : <DuplicateID>
If you use failover cluster manager on both the 2008R2 and the 2012 clusters the VM shows it is gone from the 2008R2 cluster and just fine on the 2012 cluster. I have tried everything I can think on short of removing the cluster from VMM to try
and resolve this issue and I really don't want to have to do this everytime I run into this issue. I've tried just right-clicking the VM in the VMM console and selecting "Delete" which does remove it but then it pops back in once the VMs refresh
on the 2008R2 nodes. I have tried to force the removal using "Get-SCVirtualMachine | where { $_.Name -EQ "<VM>" -and $_.Status -EQ "IncompleteVMConfig"} | Remove-SCVirtualMachine -Force" and it again pops right
back into the console. It seems to me like during the migration, SCVMM isn't cleaning up after itself and updating its database to reflect where the VM now resides. How can I permanently remove this VM that is leftover when migration between clusters without
having to remove and read the cluster to VMM?

Since nobody replied, I opened a case with MS.
The resolution to this issue is to use Hyper-V manager to connect to the node you migrated the VM from. Here you will see a VM that has only a GUID for a name and is in an incomplete state. Right click this leftover VM and delete it using Hyper-V manager.
Then go back into SCVMM and refresh both your source Windows 2008R2 and then your target 2012 clusters. This will reconcile the SCVMM database and the duplicate VM. According to MS, there is some process that didn't complete deleting this VM as part of the
migration and performing these steps cleanly resolves the issue.

Upgrade the SCVMM 2008 R2 to SCVMM 2012 R2

I am suggesting you to fresh install OS and SCVMM 2012 R2 in different server. Once you install and configured SCVMM 2012 R2 then disconnect One by one Hyper-V servers from SCVMM2008
and add in SCVMM2012 R2.
For testing purpose disconnect non critical Hyper-V server and added to SCVMM 2012 R2.

Upgrade from windows 2008 R2 to windows 2012 and Quorum

Dear Sir.
I am going to upgrade hyper-v cluster of 4 nodes 2008 r2 to windows 2012 hyper-v cluster.
i am going to evict tow node and build new cluster.
should I configure new quorum for new cluster or can i use the the quorum from old system ?
thanks

Hi,
Base on my experience, you need create a new cluster when you choose migrate the cluster, so you need the new witness disk.

¿Is it possible to upgrade from SCCM 2012 a domain controller in Windows Server 2008 R2 TO 2012 R2?

Hi all.
I want to know if is it possible to upgrade a domain controller from Windows Server 2008 r2 to 2012 r2 installing from SCCM 2012.
Thanks.
Regards.

Hi all.
I want to know if is it possible to upgrade a domain controller from Windows Server 2008 r2 to 2012 r2 installing from SCCM 2012.
Thanks.
Regards.
Anything is possible if you can script it. You could create a task sequence to do the following (with scripts):
1. Demote 2008R2 DC to member server
2. Remove 2008R2 member server from domain
3. Build new 2012R2 member server and join to domain
4. Promote 2012R2 member server to DC
You can do this. However, why would you? Just because you can doesn't mean you should. In my opinion it's more trouble and testing than it's worth. How many times would you need to do this?

Steps to upgrade from sql 2008 r2 se (nonclustered) to sql 2012 se (clustered)

hello,
I am currently running a non clustered instance of a sqlserver 2008 R2 SE and need to upgrade to a clustered instance of SQLServer 2012 SE. The underlying OS is Windows 2008 R2 SE. I already bought the second server with the same os online but havent installed
sql 2012 yet.
I am thinking of backing up my databases and script out all the logins and linked servers first.
Then upgrade the SQLServer 2008 R2 SE to 2012 SE. But can I upgrade it to a clustered instance directly? If yes then I can definitely add the other server to the cluster while installing sql.
Can someone point me to the right steps for this upgrade process
Thanks

Hello,
Direct upgrade to cluster is not possible without installing SQL server in cluster aware mode. I would recommend you need to uninstall SQL server 2008 R2 and then create windows cluster between two nodes and then install SQL server in cluster aware
mode.
You are right with taking up complete backup of all databases with logins and jobs.

[Forum FAQ]How to upgrade Windows Server 2008 R2 with a GUI to Windows Server 2012 Server Core

We found that some customers willing to upgrade Windows Server 2008 R2 GUI to Windows Server 2012 Server Core recently. This article provides detailed steps to perform the upgrade.
Analysis
Upgrading from Windows Server 2008 R2 with a GUI installation to Windows Server 2012 with Server Core directly
is not supported. If you do that, you will receive the error message below(Figure 1) in Compatibility report:
Figure 1.
In these scenario, you can upgrade to Windows Server 2012 firstly. After the upgrade process is completed, you can switch freely between Server Core and Server with a GUI modes.
Produces
You can follow the steps below to perform an upgrade from Windows Server 2008 R2 with a GUI installation to Windows Server 2012 Server Core mode:
1. Upgrade to Windows Server 2012 with a GUI mode
1) Firstly, please boot into Windows Server 2008 R2 with a Windows Server 2012 installation DVD inserted.
2) Select the operating system you want to install with a GUI mode.
We can see 2 options (Server Core Installation or Server with a GUI) for each operating system version. (Figure 2)
Figure 2.
Note: Please make sure you have enough disk space on system partition. Or you will get such an error in Compatibility report.(Figure 3)
Figure 3.
After the Compatibility check, the installation will continue. It will take several minutes until upgrading is done.(Figure 4)
Figure 4.
2. Switch the GUI mode to Server Core
Method 1: Using Server Manager
1) Open Server Manager, click
Manger and select “Remove Roles and Features” to start the
Remove Roles and Features Wizard.
2) In Features,
uncheck the box next to the “User Interfaces and Infrastructure” option, and then click “Next”. (Figure 5)
Figure 5.
Now tick the “Restart the destination Server automatically if required” box, then click “Remove”. (Figure 6)
Figure 6.
Method 2: Using Windows PowerShell
There are multiple ways to remove the GUI via Windows PowerShell, we introduce the way of using the ServerManager module.
You can also run the commands in Windows PowerShell with an administrator to remove the GUI feature:
“Import-Module ServerManager”
“Uninstall-Windowsfeature Server-Gui-Shell –Restart”
or
“Uninstall-WindowsFeature Server-Gui-Shell, Server-Gui-Mgmt-Infra –Restart”
It will take a period of time to remove the GUI feature and reboot. When the system boots up, you will get into the Windows Server 2012 with Server Core mode. (Figure 7)
Figure 7.

Want to upgrade 2008 R2 to 2012. Upgrade advisor giving errors relating to Database Compatability Level and Server Collation

I want to upgrade a SQL Server from 2008 R2 to 2012. When I run upgrade advisor, I get the following error messages:
Rule "Valid Database compatibility level and successful connection" failed.
The report server database is not a supported compatibility level or a connection cannot be established. Use Reporting Services Configuration Manager to verify the report server configuration and SQL Server management tools to verify the compatibility
level.
Rule "Valid Database server collation and successful connection" failed.
The SQL Server Database Engine is not configured with a valid server collation and cannot be used as the Reporting Services SharePoint Shared Service catalog database.
The database called ReportServer has Collation = Latin1_General_Cl_AS_KS_WS and Compatibility level = 100

Hi Andrew,
Regarding to the first error message, please check the Reporting Service Configuration Manager, make sure that you connect to ReportServer database from the correct server
and use servername\instancename format connection string. For more details, please review this similar
thread.
Regarding to the second error, it is caused by that the current SQL Server Database Engine server is using an incompatible server collation.
SQL Server 2012 Reporting Services SharePoint mode utilizes the SharePoint shared services architecture. SharePoint does not support SQL Server Database Engine configured for case sensitive or server collations or binary server collations.
And since the SQL Server Database Engine server collation property cannot be changed, you will not be able to complete an upgrade of Reporting Services. You will need to migrate your Reporting Services installation to a new server which is using a compatible
server collation. For more details, please review the following article:
Incompatible Database Engine Server Collation:

Do you recommend Server 2008 R2 to 2012 R2 inplace upgrade?

Hi
Do you recommend Server 2008 R2 to 2012 R2 in place upgrade for both DCs and member servers?
Thanks

Hi,
From the
MS support lifecycle, the mainstream support for Windows Server 2008 R2 would be end in 2015.
To upgrade to Windows server 2012 R2, please refer to the links below:

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.

Can't upgrade Windows Server 2008 R2 Enterprise to Windows Server 2012 R2 Standard

Even though the "Windows Server Installation and Upgrade" TechNet article (DN627667) claims that I can upgrade Windows Server 2008 R2 SP1 to Windows Server 2012 R2 Standard, it seems I can't. I get an error message saying "Windows 2008
R2 Enterprise cannot be upgraded to Windows Server 2012 R2 Standard (Server Core Installation). You can choose to install a new copy of Windows..." What might be causing this issue? Thanks for any input! :)

Hi,
Firstly, for retail versions, Windows Server 2008 R2 Enterprise with SP1 can be upgraded to Windows Server 2012 R2 Standard/Datacenter.
I assume you are running Windows Server 2008 R2 retail version, right?
In addition, it seems that in earlier version than Windows Server 2012,
once you install the server in Core or with GUI mode, you could not switch to the other. The only option was to rebuild the server from scratch.
Did you install Windows Server 2008 R2 in GUI? If yes, I recommend you to upgrade it to Windows Server 2012 R2 in GUI
mode to see if the issue persists. If it succeed and you want to run in server core, you can just remove the graphical shell and convert your Windows Server 2012 R2 to Server Core.
Best regards,
Susie
Thanks for replying Susie. The 2008 R2 software is the one provided by Microsoft for Action Pack subscribers, so I'm assuming it's not retail. That's another thing, I think I should be installing the GUI as my 2008 has a GUI, not just the server core. For some
reason I missed that and clicked on the server core only install!
