In-place Windows server 2008 r2 upgrade to 2012 r2 on an HP Proliant DL380 G5 server.

Medium Priority
Last Modified: 2020-06-02
Is it possible perform an in-place Windows Server 2008 r2 upgrade to 2012 r2 on an HP ProLiant DL380 G5 Server ?

The reason I ask, I have been installing many HPE ProLiant DL 360p G8 servers running Windows server 2016. As always, I've always been following HP's guidelines for support recommendations
doing so, I’ve retired several perfectly running HP ProLiant DL380 G5 Servers because Windows server 2008 R2 is no longer supported

I have a client that owns a small law firm currently still running an older HP ProLiant DL380 G4 Server running Windows server 2000 R2.  

Knowing that Windows server 2012 R2 is still supported, I would like to install an HP ProLiant DL380 G5 Server with a fresh copy of Windows server 2008 R2 and perform an in-place upgrade to Windows server 2012 R2.
I've never done this with a server.

Would like to get input and recommendations. I've googled this and I see a few folks have done this successfully. It appears that most if not all drivers from 2008 R2 will be supported on the 2012 R2 platform. I'm not concerned with the iLo drivers
-      the fact that this server will not be running any specific databases and will basically just be housing word documents, spreadsheets and JPEG's, I would like to make use of these excellent and trouble-free servers for another couple years.

Please note: I know I’ll get feed back referencing using cloud or virtual services. I do have a few clients that I have set up using SharePoint. I'll be moving more into cloud-based solutions down the road

Any input and recommendations will be greatly appreciated

I would not expect any major issues when upgrading W2008 R2 to 2012 R2. Missing drivers can be downloaded from internet. Software you've mentioned should also be OK. Even after Windows Server 2012 R2 Extended support period end the software should work... If you are not sure just create the boot drive image before the upgrade and you may restore it any time later.

More important are hard drives on the computer. Their life is not indefinite and some sources are saying 3 years of intensive spinning should be enough... So think about the HDD replacement if you plan several more years of computer life.

"with a fresh copy of Windows server 2008 R2 and perform an in-place upgrade to Windows server 2012 R2 "
Why are you doing the fresh copy then upgrade?  Why not just to a fresh install of 2012 R2?

The usual reason to do an in-place upgrade (generally discouraged on EE for servers) is to preserver applications and configuration.  If you're starting with a fresh copy of 2008 R2, there should be nothing to preserve.

The reason I am performing an in-place upgrade is because many times, the newer operating system will work with existing older drivers. HP doesn’t provide driver support for 2012 on g5

trying to perform a brand new 2012 install would require 2012 drivers which there aren’t any. It is always my preference to start with a fresh operating system if possible.

As far as the hard drives. I always create two mirrored partitions and have online spares available. I’m using hot swap Sas drives.

My main focus is to confirm if 2012r2 will be supported on the server even though it’s not approved by HP. I was thinking In-place upgrade would be the most reliable way to get 2012 or two working

Andreas, install 2012 R2. Windows will pick missing drivers from the internet automatically as soon as it's connected. If that fails, you may still try older drivers.
