Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. An in-place upgrade allows you to go from an older operating system to a newer one while keeping your settings, server roles, and data intact. This article will teach you how to move to a later version of Windows Server using an in-place upgrade.

We recommend that you collect some information from your devices for diagnostic and troubleshooting purposes in case the upgrade is unsuccessful. We also recommend you store the information somewhere you can get to even if you can’t access your device. Open an elevated PowerShell prompt, make a note of your current directory, and run the following commands. Using File Explorer , navigate to the directory you noted down, and copy the files to a USB flash drive or network location off of your computer.

Get-ComputerInfo requires PowerShell 5. If your Windows Server version doesn’t include Powershell you can find this information in the registry. After you’ve collected all of your Windows Server-related information, we recommend that you backup your server operating system, apps, and virtual machines.

You must also shut down, quick migrate, or live migrate any virtual machines currently running on the server. You can’t have any virtual machines running during the in-place upgrade.

Now you’ve completed your prerequisites and collected diagnostic information, you’re ready to perform the upgrade. Wait for a while and click Install to start upgrading.

After finishing, your PC will automatically restart. It also has some conspicuous limitations such as the 2 TB limit for backup, the numbers of backups it could keep, the lack of individual file backup feature, etc.

It has different editions, and the Server edition is specially designed for Windows Server. For instance, you can create scheduled incremental or different backup , set up retention policy to auto delete older backup, restore system image to different hardware, etc. And the operation is much simpler than WSB. Moreover, it contains Sync features to copy your data with original format and structure, Clone features to duplicate hard drive and therefore migrate Windows Server to SSD.

Have a try and find more practical tools. Click Backup on the left pane and choose a backup type. Optionally, you can also use System Backup in case of upgrade failure. Tap Add Folder or Add File to select the data you want to backup, then specify a destination to store it. For the destination path, you can choose to Select a network location or Select a cloud in the drop-down menu. After that, you can manage more settings to customize the backup, and then Start Backup.

Options: Manage compression level, image splitting, backup encryption, comment, email notification, etc. With this simple operation, you could backup whatever you want to keep before upgrading Windows Server r2 to Thus even if something goes wrong in the process of upgrading, you can easily retrieve important files or restore the operating system to an earlier state. Besides, if you want to upgrade Server or to through clean installation, backup is especially essential.

Migration means moving from your existing operating system to Windows Server R2 by transferring to a different set of hardware. The table below briefly summarizes which already licensed that is, not evaluation Windows operating systems can be upgraded to which editions of Windows Server R2. In-place upgrades from bit to bit architectures are not supported.

All editions of Windows Server R2 are bit only. Upgrades from pre-release versions of Windows Server R2 are not supported. Perform a clean installation to Windows Server R2. If you do not see your current version in the left column, upgrading to this release of Windows Server R2 is not supported.

If you see more than one edition in the right column, upgrade to either edition from the same starting version is supported. Even in supported upgrade paths from previous retail versions to Windows Server R2, certain server roles that are already installed might require additional preparation or actions for the role to continue functioning after the upgrade.

Consult the specific TechNet Library topics for each server role you intend to install for details of additional steps that might be required. Similarly, you can convert the evaluation version of Windows Server R2 Datacenter to the retail version. Before you attempt to convert from evaluation to retail, verify that your server is actually running an evaluation version.

To do this, do either of the following:. From an elevated command prompt, run slmgr. From the Start screen, open Control Panel.

This video also looks at some of the upgrade paths that are available. In-Place Vs Migration A migration is when the documents and settings are manually copied over and the applications are re-installed. Migration tools have existed in previous versions of Windows Server, however in Windows Server these migration tools upgrade windows server 2012 datacenter to r2 free been improved. A migration also allows individual items to be migrated.

For example, dataceenter single role can be migrated to any server. The advantage of a migration is that in 2r cases particular fre may be left behind and not migrated. For example, if the user profile on the server is causing performance problems on derver server, migrating only больше информации role to another server means the old profile is left behind and thus so is the problem. In-Place Upgrade Not Supported A upgrade windows server 2012 datacenter to r2 free is when the documents and settings are manually copied over and the applications are re-installed.

In-Place Upgrade Not Supported In order to perform an in-place uograde you must be running the same architecture. Windows Server does not come in an Itanium or 32bit version so therefore no upgrade path is available.

The version of Windows must be one that was released to manufacture and thus pre-releases, evaluations or preview editions are eerver supported. Also, it must be running upgrade windows server 2012 datacenter to r2 free same interface, e.

However the interface can be changed after the in-place upgrade. Also the upgrade must be in the same language. If you are upgrading to Windows Server you will need to be running Windows Server or above.

If you are running the Standard or Enterprise editions of Window Serverthis can be upgraded to the Standard or Datacenter editions of Windows Server Datacenter is available in Windows Server and so it is a straight upgrade.

Web server does not exist on Windows Server so this needs to upgraded to Windows server standard. Windows Server requires service pack 2 to be installed before the upgrade and Windows Server R2 requires service pack 1 to be installed before the upgrade.

Upgrade paths to Windows Server R2 Upgrade paths to Windows Server R2 are the same as before, except the operating system must be running Windows Server R2 with service pack 1 installed. In other words, upgrades to Windows Server R2 are not supported on Windows Server or earlier. These are standard to standard or datacenter and datacenter to datacenter. Upgrades from Essentials and Foundation are not supported.

Tips for an easy upgrade from Windows Server to Windows Server R2 | TechRepublic

 

This section covers disk space requirements only for upgrading domain controllers from Windows Server or Windows Server R2. For more information about disk space requirements for upgrading domain controllers to earlier versions of Windows Server, see Disk space requirements for upgrading to Windows Server or Disk space requirements for upgrading to Windows Server R2. Size the disk that hosts the Active Directory database and log files in order to accommodate the custom and application-driven schema extensions, application and administrator-initiated indexes, plus space for the objects and attributes that you will be added to the directory over deployment life of the domain controller typically 5 to 8 years.

Right sizing at deployment time is typically a good investment compared to greater touch costs required to expand disk storage after deployment. On domain controllers that you plan to upgrade, make sure that the drive that hosts the Active Directory database NTDS. DIT file before you begin the operating system upgrade. If there is insufficient free disk space on the volume, the upgrade can fail and the upgrade compatibility report returns an error indicating insufficient free disk space:.

In this case, you can try an offline defragmentation of the Active Directory database to recapture additional space, and then retry the upgrade. In previous releases, Windows Server editions differed in their support of server roles, processor counts and large memory support.

The Standard and Datacenter editions of Windows Server support all features and underlying hardware but vary in their virtualization rights – two virtual instances are allowed for Standard edition and unlimited virtual instances are allowed for Datacenter edition.

The following Windows client and Windows Server operating systems are supported for domain member computers with domain controllers that run Windows Server or later:. You cannot upgrade domain controllers that run Windows Server or bit versions of Windows Server To replace them, install domain controllers that run a later version of Windows Server in the domain, and then remove the domain controllers that Windows Server Note that you cannot convert a domain controller that runs an evaluation version of Windows Server directly to a retail version.

Instead, install an additional domain controller on a server that runs a retail version and remove AD DS from the domain controller that runs on the evaluation version. Due to a known issue, you cannot upgrade a domain controller that runs a Server Core installation of Windows Server R2 to a Server Core installation of Windows Server The upgrade will hang on a solid black screen late in the upgrade process.

Rebooting such DCs exposes an option in boot. An additional reboot triggers the automatic rollback to the previous operating system version. Until a solution is available, it is recommended that you install a new domain controller running a Server Core installation of Windows Server instead of in-place upgrading an existing domain controller that runs a Server Core installation of Windows Server R2. For more information, see KB article Windows Server requires a Windows Server forest functional level.

That is, before you can add a domain controller that runs Windows Server to an existing Active Directory forest, the forest functional level must be Windows Server or higher. This means that domain controllers that run Windows Server R2, Windows Server , or Windows Server can operate in the same forest, but domain controllers that run Windows Server are not supported and will block installation of a domain controller that runs Windows Server If the forest contains domain controllers running Windows Server or later but the forest functional level is still Windows , the installation is also blocked.

Windows domain controllers must be removed prior to adding Windows Server domain controllers to your forest. In this case, consider the following workflow:. The new Windows Server domain functional level enables one new feature: the KDC support for claims, compound authentication, and Kerberos armoring KDC administrative template policy has two settings Always provide claims and Fail unarmored authentication requests that require Windows Server domain functional level.

The Windows Server forest functional level does not provide any new features, but it ensures that any new domain created in the forest will automatically operate at the Windows Server domain functional level. The Windows Server domain functional level does not provide other new features beyond KDC support for claims, compound authentication, and Kerberos armoring.

But it ensures that any domain controller in the domain runs Windows Server After you set the forest functional level to a certain value, you cannot roll back or lower the forest functional level, with the following exceptions: after you raise the forest functional level to Windows Server , you can lower it to Windows Server R2.

If the forest functional level is set to Windows Server R2 , it cannot be rolled back, for example, to Windows Server After you set the domain functional level to a certain value, you cannot roll back or lower the domain functional level, with the following exceptions: when you raise the domain functional level to Windows Server R2 or Windows Server , and if the forest functional level is Windows Server or lower, you have the option of rolling the domain functional level back to Windows Server or Windows Server R2.

If the domain functional level is set to Windows Server R2 , it cannot be rolled back, for example, to Windows Server Beyond functional levels, a domain controller that runs Windows Server provides additional features that are not available on a domain controller that runs an earlier version of Windows Server.

For example, a domain controller that runs Windows Server can be used for virtual domain controller cloning, whereas a domain controller that runs an earlier version of Windows Server cannot. But virtual domain controller cloning and virtual domain controller safeguards in Windows Server do not have any functional level requirements. Microsoft Exchange Server requires a forest functional level of Windows server or higher.

AD DS cannot be installed on a server that also runs the following server roles or role services:. Though they are not operations master roles, another change in AD DS installation is that DNS server role and the global catalog are installed by default on all domain controllers that run Windows Server Improvements in AD DS beginning in Windows Server enable safer virtualization of domain controllers and the ability to clone domain controllers.

Cloning domain controllers in turn enables rapid deployment of additional domain controllers in a new domain and other benefits. The following table covers common Active Directory-integrated Microsoft applications. The table covers what versions of Windows Server that the applications can be installed on and whether the introduction of Windows Server DCs affects application compatibility.
