But, you aren't sure if your current hardware meets its requirements for this operating system or if you should upgrade it as well. Making sure if you have the right specs is a must. To run server R2, your hardware must meet certain requirements to run it. It requires a bit processor unless you're running on Itanium based systems.
Your processor must run on at least a 1. It's recommended your processor is 2. The least amount of available disk space you need to run it is 10 GB. For best performance, we suggest you've 40 GB or more of disk space available for the system to run better. The display requirement for this operating system is at least a Super VGA by monitor or one with better resolution.
To run the system you'll need the basics. The keyboard and mouse are essential to run this operating system. If you're running the server on an Itanium-based system, you'll need to meet certain hardware requirements. Your system must have an Intel Itanium 2 processor and more disk space available.
When the computer running the system has more than 16 GB of RAM, it'll need more free disk space too. The system will use these resources for dump files, paging, and hibernation. When it comes to memory, there are maximum limits you can't exceed. It is the least expensive of the various editions and lacks some of the more advanced functionality typically found in the higher end editions such as full Active Directory support and Hyper-V virtualization capabilities.
In addition, the Foundation edition limits some of the included features, such as restricting the number of concurrent remote desktop services connections to 50 and is able to access a maximum of 1 processor and 8GB of RAM. As previously stated, whilst the original version of Windows Server supported both bit and bit versions, the R2 version supports only bit processors.
Windows Server is primarily targeted at small and mid-sized businesses SMBs and is ideal for providing domain, web, DNS, remote access, print, file and application services. Support for clustering, however, is notably absent from this edition.
As with Standard Edition both bit and bit versions are available. Windows Web Server R2 is essentially a version of Windows Server R2 designed primarily for the purpose of providing web services.
Now that we have covered in general terms the various different editions of Windows Server R2 we can now look in a little more detail at a feature by feature comparison of the four different editions. This is outlined in the following feature matrix:. 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 R2, you can upgrade it to Windows Server However, not every older operating system has a pathway to every newer one. Upgrade works best in virtual machines where specific OEM hardware drivers are not needed for a successful upgrade. 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.
Before you get started with an upgrade, have a look at the tables on this page to see how to get from where you are to where you want to be. For information about the differences between the installation options available for Windows Server Technical Preview, including the features that are installed with each option and the management options available after installation, see Windows Server Whenever you migrate or upgrade to any version of Windows Server, you should review and understand the support lifecycle policy and timeframe for that version and plan accordingly.
You can search for the lifecycle information for the particular Windows Server release that you are interested in. For details, including important caveats and limitations on upgrade, license conversion between editions of Windows Server , and conversion of evaluation editions to retail, see Supported Upgrade Paths for Windows Server Note: Upgrades that switch from a Server Core installation to a Server with a Desktop installation or vice versa are not supported.
If the older operating system you are upgrading or converting is a Server Core installation, the result will still be a Server Core installation of the newer operating system. Quick reference table of supported upgrade paths from older Windows Server retail editions to Windows Server retail editions:. You can convert the evaluation version of Windows Server Standard to either Windows Server Standard retail or Datacenter retail.

Quick reference table of supported upgrade paths from older Windows Server retail editions to Windows Server R2 retail editions:.
For details, including important caveats and limitations on upgrade, and conversion of evaluation editions to retail, see Evaluation Versions and Upgrade Options for Windows Server To ensure no gap in support, you need to upgrade to a supported version of Windows Server, or rehost in Azure by moving to specialized Windows Server R2 VMs.
For on-premises servers, there is no direct upgrade path from Windows Server R2 to Windows Server or later. As you are planning your upgrade, be aware of the following guidelines for the middle step of upgrading to Windows Server R2.
You can't do an in-place upgrade from a bit to bit architectures or from one build type to another fre to chk, for example. In-place upgrades are only supported in the same language.
You can't upgrade from one language to another. You can switch your upgraded server core installation to Server with Full Desktop, but only on Windows Server R2. Windows Server and later do not support switching from server core to Full Desktop, so make that switch before you upgrade to Windows Server For more information, check out Evaluation Versions and Upgrade Options for Windows Server , which includes role-specific upgrade details.
