Moving farm from Windows 2008 R2 to Windows 2012 (R2?)

I've been asked to move our current small SP2010 Server farm (WFE, App, and SQL) from Windows 2008 R2 servers to new Windows 2012 servers.
Any limitations that would prevent this from happening? Any major differences? Installation through the GUI won't be a problem? Any benefits to tout? I've installed 2012 R2 on a HyperV but haven't messed around with it much beyond that.
Thanks,
Scott

For SharePoint 2010, I would suggest sticking to 2008 R2. It is the most well tested operating system for SharePoint 2010. There may be some unknown gotchas that the community is unaware of with Server 2012 or 2012 R2.
Otherwise, everything should 'just work' with SP2 media.

SharePoint 2013 Server OS upgrade from Windows 2008 R2 to Windows 2012 R2

Is it possible to have SharePoint 2013 farm to have mixed version of OS (Windows 2008 R2 and Windows 2012 R2).
We have a request to upgrade our farm servers from WIN 2008 R2 to Win 2012 R2. We have 5 servers in farm -
2 App servers - running with Central Admin, Service Applications, User Profile
3 Web Front End Servers- running web application, search and workflow manager
the database layer is separate on sql 2012 R2
We want to upgrade OS from windows 2008 R2 to windows 2012 R2 and SQL to SQL 2014.
What will be right approach to do OS upgrade in above scenario to minimize the impact of downtime.
May be add windows 2012 based servers in farm one by one and replace the windows 2008 R2 based servers from server.
Regards,
Kunal Abrol

Its possible, but I wouldn't recommend it. The problem is that you can only install SharePoint 20103 on Windows Server 2012 r2 using the slipstreamed SP1 version. I assume that you used the regular version to install on you Server 2008 r2 versions.
Even if you upgrade those servers to SP1 there are some minor differences in the builds between slipstreamed SP1 and upgraded SP1. So although it will work it isn't recommended.
Also, you should be aware the upgrade of inplace SharePoint servers running Windows 2008 r2 to Windows 2012 r2 is not supported.
To upgrade to server 2012 you'll need to add 2012 servers to your environment using the slipstreamed version os SharePoint and then remove the old server 2008 r2 servers as soon as possible. For the period of the upgrade you should be able to get away
with running the farm in a mixed state.

Inplace upgread Windows 2008 R2 to Windows 2012

Hello,
I am testing inplace upgrade from Windows 2008 R2 to Windows 2012 R2. My test server is Windows 2008 R2 Enterprise, Evaluation and is a domain controller. I tried to perform an inplace upgrade, however it failed. The compatibility report says that
Windows Server 2008 R2 Enterprise cannot be upgraded to Windows Server 2012 R2 Datacenter Evaluation (Server with GUI).
I also update the schema first. It went fain and it was completed without error.
Thank you.

Hi,
Based on my experience, it is not supported to upgrade
from a Windows server evaluation version to another Windows server evaluation version. If you want to use Windows server 2012 R2 Datacenter evaluation version, you need to delete the previous operate system and perform a clean installation. Or
you can convert the evaluation version of Windows Server 2008 R2 to a full retail version and then upgrade it to Windows server 2012 R2 Datacenter version.

Migration of AlwaysON database from WSFC 2008 + SQL2012 to WSFC 2012 + SQL2014

Hello All,
I have a 6 node GEO cluster, 4 nodes in primary site + 2 nodes in secondary site. In the primary node 03 and 04 has 2 pair of SQL instances default + named.
I am planning to move the named SQL pair from WSFC 2008 + SQL2012 TO WSFC 2012 + SQL2014. It has only one AG group with 4 TB of DBs.
Do you guys have any experience and options for this migration. I am planning to go with backup/restore. Let me share yours inputs.
1. Backup/restore 2. cross cluster migration 3.Detach/attach 4. SAN migration
Thanks!

Helping SQL DBAs and Developers >>> SqlserverBlogForum

Since WSFC does not support rolling upgrades, you will need to have another WSFC running Windows Server 2012/R2 (R2 is highly recommended due to the features available for maintaining high availability) and do a cross-cluster migration. Refer to this documentation
for more details.
https://msdn.microsoft.com/en-us/library/jj873730.aspx
This requires that you're fairly comfortable with PowerShell.
The main challenge here is dealing with hardware resources since you will need additional servers when moving into the new WSFC. You would have to run multiple instances on the same cluster node while you remove a node and repurpose it for WSFC 2012/R2.
This is where proper planning is very important to make sure you are maximizing your resources while minimizing downtime. I cannot speak about the capabilities of your SAN as each vendor will have different features but my approach has always been dependent
on SLAs and recovery objectives. Backup/restore will still be needed to synchronize your data from the old WSFC to the target WSFC.

Migration of DNS from Windows 2008 R2 to Windows 2012

Hello,
We have a pair of Windows 2008 R2 servers running authoritative DNS services (they are not AD controllers, neither used as resolvers). There are ~20 domains + 10 DNSSEC domains hosted on those servers. We're considering to migrate them to Windows 2012
servers and retain IP addresses.
I'd greatly appreciate if somebody could advise the basic steps for such migration (particularly the DNSSEC part).
Many thanks.

Hi,
It worked for me with a test zone but my example only had a single A record. You should test this first by adding the zone and testing resolution on the 2012 server before deleting it from the 2003 server.
The bug for secondary zones that you describe in Server 2008 is news to me. However, 2012 and 2012 R2 has many advantages over 2008 R2 for DNSSEC signed zones so I would recommend you migrate even if you weren't having problems on 2008 R2.
If you've been following the thread you mentioned above, you know that I've been doing a lot of testing with signed zones being updated on secondary servers. The signed zone is *always* updated on a secondary server but if the change on the primary was only
a signature refresh then as of right now there is still a bug where the newest RRSIGs are not transferred to the secondary server. This happens because the zone transfer occurs just before the new RRSIG is generated on the primary. This causes it to be left
behind on the primary server unless there is another zone transfer afterward. Note that a zone transfer still happens, it just happens too soon. The zone transfer that happens is an incremental zone transfer.
If the previous RRSIG expires before another zone transfer occurs then the zone can have validation problems on the secondary. There is a hotfix for this that will be distributed soon. I am checking now on the date.
If you increment the serial # on the primary, the secondary should get a full zone transfer.

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.

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
Peter

Windows 2008 Server and Windows 8 clients

Hey Guys,
I have had this problem for sometime now and really need a solution. I have Windows 2008 Enterprise Server running about 200+ terminal services clients. All Windows XP clients are fine, Windows 7 clients have issues when they get an updated version of
remote desktop client(to solve the issue we simply rollback the update), Windows 8 clients cannot connect and use out remote app. The issue stems from the newer version of remote desktop client (on windows 7 and embedded in windows 8) cannot connect to our
terminal server and generates an error and immediately disconnects. The error says "
Your computer can't connect to the remote computer because an error occurred on the remote computer that you want
to connect to
So my questions are, how can i update my Windows 2008 Terminal server version to support these clients, or do u have migrate to Windows 2012? Or is there a solution to my current problem which will allow my client to connect and use the remoteapps?

Hi,
Thank you for posting in Windows Server Forum.
Please follow the below steps and verify result.
LAN manager authentication level settings (Local security policy->Local Policies->Security Options->Network Security: LAN Manager Authentication level).
Try to change it to "Send NTLMv2 response only"

Windows 2008 Server R2 Windows Explorer Refresh Issue

I work on a Windows 2008 R2 server that I connect to through remote desktop. Recently the automatic refresh in Windows Explorer stopped working. If I create, delete, copy, move, rename etc., I do not see the changes unless I refresh (F5). I tried the three
solutions below which was for Windows 7, but they have not fixed the problem. Can anyone please help me.

You can unmark no problem.
You tried with 0x0 ? In my first post I did a error to write down 0x1. From there, if it does not work we will continue.
They are other key too that might work;
NoRemoteChangeNotify = 1 (DWORD) in the same location as thee other.
and NoSimpleNetIDList = 1 (DWORD) from HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

"Software Usage Metrics initialize failed" error when open Report Manager, after moving ReportServer from SSRS 2008 to SSRS 2012 (Native Mode)

I've asked this question in SQL Server Upgrade forume, I'm asking here as well:
Your help is highly appreciated!
After migrating ReportServer db from 2008 to 2012, when access Report Manager throughhttp://myserver:80/Reports, I got the error below:
ui!ReportManager_0-3!11d8!02/04/2013-15:19:12:: e ERROR: Software Usage Metrics initialize failed
The process is below:
•I successfully installed SQL Server 2012 (64-bit) Enterprise as a Native Mode on a server who runs Windows 7 Enterprise SP1 (64-bit).
•I restored "ReportServer2008To2012" and "ReportServer2008To2012TempDB" in SSRS 2012 from the db files backed up in SQL 2008. In SSRS 2008, I have SSRS Model, ad-hoc reports based on model, and I also have canned reports built through BIDS
report server project.
•I reconfigured both databases' Compatibility level to SQL Server 2012(110) from SQL Server 2008(100).
•I configured SSRS through Reporting Services Configuration Manager as below:
> I chosen "Use built-in account:" as Service Account
> In "Database" tab, I selected "Choose an existing report server database" and choose "ReportServer2008To2012" db, I used "Windows Authentication" (my login has the System Administrator priviledge). I got all 4 parts
success: Verifying database sku = Success; Generating rights scripts = Success; Applying connection rights = Success; Setting DSN = Success.
> I went to "Scale-out Deployment" to check if the initializing succeed, I found nothing there.
Here are what I did from different approaches:
A •I went to "Encryption Keys" and restored the key I backed up from SSRS 2008, after retoring, I got two initialized instances: One is on my current server (SSRS 2012), the other one is from the old server (SSRS 2008).
   I deleted the old one(SSRS 2008) through "Remove Server" action and kept the one on my current server(SSRS 2012).
   After I restart SSRS service, and tried to connect Report Manager, I got "An internal error occurred on the report server. See the error log for more details."
   I checked the log file, the error is actually "ERROR: Software Usage Metrics initialize failed"
B •I also tried to "Delete Encrypted Content" and did see the SSRS was initialized through checking it on "Scale-out Deployment", however when I tried to open Report Manager, I got the same error.
Anyone had the same issue? Any solution? Thanks in advance!

How to Upgrade Service Manager 2012 SP1 with Windows 2008 R2 to SCSM 2012 R2 with Windows 2012 R2

Hi,
We are using Service Manager 2012 SP1 UR2 with Windows 2008 R2.
I am planning to upgrade Service Manager to R2 with Windows 2012 R2. I found the steps to upgrade SCSM 2012 Sp1 to R2 but need assistance to upgrade with 2012 R2 OS.
Please suggest how to achieve the above mentioned objective.
Regards, Syed Fahad Ali

Virtualization solves this problem handily, by allowing you to create a new server to run the new program on the same hardware. it also solves the related problem of moving off unsupported hardware without changing OS or application. VMware is my personal
favorite, but Hyper-V, Xen, and VirtualBox all have similar capabilities.
Compare the cost of work and confidence in success of a upgrade, where any of thousands or millions of uncontrolled settings could cause an issue, to the cost of work and confidence in success of installing a new OS instance and configuring a known state
for the new environment.
In short, upgrades should no longer be a thing. there are just too many ways they can go wrong, and it's far too easy to create a new OS with minimal expense and effort.

Windows 2008 R2 SP1 Windows update not applicable

HELP!!! We have 3 Windows 2008 R2 servers that were updated with SP1 back in March. Last month we noticed on our Retina audit that the three servers were missing several Windows critical patches that were released after SP1 was applied. WSUS did not report
any missing patches for those three servers. When we tried to manually apply those missing patches we get the error message "This update is not applicable to your computer". After some troubleshooting we found that KB976932 (Service Pact 1) is not listed in
installed updates. However, system property shows Windows 2008 R2 SP1 Enterprise Edition. We are certain that SP1 did NOT come pre-installed. Microsoft Baseline Security Analyzer detected no missing patches. Microsoft System Readiness Tool CBA logs show no
errors. Ran SFC /SCANNOW and found no error also. Force install of the patches with command switch /wuforce, did not work we still get the same message patch not applicable. We compared our servers that are fully patched running Windows 2008 R2 SP1 against
the three unpatched servers and found several dll and sys file's version to be different. Those dll and sys files are also the files that would have been updated by the critical patches. The only thing different between the fully patched Windows 2008 R2 SP1
servers and the unpatch are the unpatch have no public internet access. We confirmed patches that were required prior to SP1 push are installed: KB2454826 KB2534366 KB2533552 KB976902 Confirmed: Partition with Windows 2008 R2 SP1 installed is set to "ACTIVE"
Windows Event Collector service is started Windows Modules Installer is started Uninstalling SP1 is not possible because the KB976932 is not listed and verified "not hidden" in installed updates list. Rebuilding the three servers are the very last option,
since they are critical. Other than the missing patches.... the servers are running great, we have no reported issues with the three servers. Attempt to reinstall SP1 failed after reboot, error 0X800F0826. If anyone has experience this problem and know of
a solution please help.

Hi,
I would like to confirm that what updates are not applicable for your three Windows Server 2008 R2 SP1 servers?
Based on the current situation, please run the System Update Readiness Tool as Meinolf Weber mentioned and check the CheckSUR.persist.log for the corrupted
files. After that, please refer to the following Microsoft TechNet article for how to repair them.
Advanced guidelines for diagnosing and fixing servicing corruption

VM windows 2008 Cluster on Hyperv 2012 Server FC Disk error after Live Migration of the active VM Cluster Node

Deployed a 2 nodes Windows 2008 R2 SP1 Failover Cluster on a HyperV 2012 Server cluster deployed on IBM HS23 blade.
Disk susbsystem is IBM Storwize V7000. MPIO driver installed plus IBM DDSM.
Lun presented to the VM are connected with Virtual FC Adapter and everything works fine in the cluster until we start a live migration of the VM which hold the cluster disks online.
After migration complete positively, at the moment the MPIO of the migrated VM goes crazy with a lot of errors (source: mpio eventID 16 ) and warnings (source: mpio EventID: 17) in the system event log. After that the disks becomes unavailable.
Consequently everything hangs until power off the migrated vm, so the services on the cluster switchs on the second node.
I try to set the registry key HKLM\CurrentControlSet\Services\Disk\TimeOutValue to 190 as i found on various articles but nothing seems to change....
Any idea?
