Estimados: Estamos instalando windows server 2008 en un server nuevo y me encuentro con un dilema; tengo clave de windows server 2008 y al parecer no funciona en windows server 2008 r2. Lo que tengo impreso de Microsoft es lo siguiente: Windows server 2008 Std/Ent KMS type: VL2: Esta licencia no la usamos nunca porque teniamos activo el server 2003, ahora migramos y necesito activar. Yo instalé el R2 en version trial de 180 dias por el momento. En caso de que no sirva la licencia, me podría alguien decir si hay manera de cambiarla para el R2? Saludos. EDITO: En otra hoja encontré la confirmacion de compra de licencias open de MS y tengo lo siguiente: Windows Server Standard 2008 Sngl OPEN No Level - Cantidad 2 Tambien tengo exchange y vista pero no las usamos. Windows server dice cantidad 2, puedo usar dos servers con la misma clave? Recien me estoy metiendo en el tama de las licencias, y yo no estaba cuando hicieron ese contrato. Saludos.

You cannot convert your 2008 license key to 2008 R2 they are different products and there is no upgrade path. You need to access your server 2008 software through Microsoft volume licensing where you should be able to download it. I am afraid you will need to reinstall the server. The "2" should indicates you have 2 volume licenses. https://www.microsoft.com/licensing/servicecenter/home.aspx Bing Translation: No se puede convertir su licencia de 2008 clave para 2008 R2 son productos diferentes y no hay ninguna ruta de actualización. Necesita acceder a su software de servidor 2008 a través de licencias por volumen de Microsoft donde usted debería poder descargarlo. Me temo que deberá volver a instalar el servidor. El "2" debe indica tiene 2 licencias por volumen.Rob Williams

Thanks for your response. I don't understand two things: We have licence for windows 2008 std or enterprise? because it says Windows server 2008 Std/Ent KMS The other: Do we have to purchase a licence to server 2008 or microsoft can provide us with a new licence? Dont matter if i have to reinstall the OS, because we install to try some applications and meanwhile we are upgrading the hardware of the server. Thanks again! Regards.

The software download for enterprise and standard is the same it will show Windows server 2008 Std/Ent but the license should specify enterprise or standard. Microsoft will not replace your 2008 license with a 2008 R2 license.Rob Williams

So we have to install windows server 2008 std, or purchase an r2 licence... any big difference between versions? its for run sql server 2008 only.

Correct on your options. Though for running SQL, I don't believe there are a lot of differences with 2008 R2, it is quite different. Vista and 2008 are built on the same platform, and Server 2008 R2 and Win 7 are similar. The primary gains that I find advantages with 2008 R2 are Virtualization, Remote Desktop Services, and management.

Hi again, in Microsoft Licensing Web page, option Licenced Products, appears Windows Server 2008 R2 Enterprise... Can i install it legaly then?

If the license shows 2008 R2 Enterprise you can legally install without a problem.Rob Williams

We have an enterprise agreement, and if i log into licensing webpage, in download licensed products appears windows 2008 r2. I have not the serial, but i can view in license menu if i have license for that. The licensing account its not mine and i cannot log in right now.

The web page may show it for download but you are only allowed to use it, and it will only be able to activate it if you have the appropriate licensing key.Rob Williams

Thanks for all the information. Regards.
