Hi Experts,

I have an older server WIN2008 , NOT R2.
Can you show me the upgrade path to WIN2012 R2 ?
Do I have to do it in more steps ?

Hi

There is no upgrade path for 2008. You need R2 at least and next, all 2012R2 are 64 bit.

So if you are running 2008 32bit, it is the end of the line. If you are running 2008 64 bit you can upgrade to 2008 R2, from there you can upgrade to 2012R2

Please reference - Supported Upgrade Paths.

You are running:  Windows Server 2008 Standard with SP2 or Windows Server 2008 Enterprise with SP2
You can upgrade to these editions:  Windows Server 2012 Standard, Windows Server 2012 Datacenter

Upgrade:
If you want to keep the same hardware and all the server roles you have set up without flattening the server, upgrading is the way to go—and there are lots of ways to do it. In the classic upgrade, you go from an older operating system to a newer one, keeping your settings, server roles, and data intact. For example, if your server is running Windows Server 2012, you can upgrade it to Windows Server 2012 R2. However, not every older operating system has a pathway to every newer one.
You can upgrade from an evaluation version of the operating system to a retail version, from an older retail version to a newer version, or, in some cases, from a volume-licensed edition of the operating system to an ordinary retail edition.

There are a number of Microsoft Articles that say you cannot upgrade from Server 2008 standard to Server 2012 R2. You have to backup and install fresh. Patrick above is correct.

Thanks John, i am also confident my answer is correct, Eprs_Admin and Lee Ingalls are obviously not aware Server 2012 and Server 2012R2 are two completely different stories.

@Eprs_Admin, once you request the question to be closed i will protest since the choosen answer is wrong.

I am aware they are two different animals as I still manage several 2008 r2. I was simply referencing Microsoft's Technet document stating there is an upgrade path. If erroneous then I'm fine rescinding the answer. Thanks guys.

I did now the upgrade from WIN2008 to WIN2012 and then again to 2012R2.

In this case Patrick cannot be right, because it is possible to upgrade from 2008 to 2012.

Sorry Patrick,

you wrote

And this is not true.
Because I did the upgrade from WIN2008 to WIN2012.
And I mean NOT R2.

Hi Patrick,

and you wrote this :

About 32bit system you are right. But the rest is also not true.
In the microsoft articleyou can read the upgrade path and I did like this.

Hi John,

your document belongs to WIN2008 R2.
But this is not my question.
I was asking for WIN2008 , not R2.

And so we all do at EE, i always say to my wife "if you don't understand the term upgrade path then bring me a nice cold beer and talk about something else".
