Objectives This guide describes how to perform an in-place upgrade of Windows Server by: Planning the in-place upgrade Performing the in-place upgrade Troubleshooting the in-place upgrade Cleaning up after the in-place upgrade Costs There is no charge for performing an in-place upgrade of Windows Server.
You are only charged for the resources consumed during the upgrade, including: Compute Engine Use the pricing calculator to generate a cost estimate based on your projected usage. Before you begin The guide assumes that you have basic knowledge of: Compute Engine Performing unattended Windows Server installations by using Windows Setup. Plan the in-place upgrade Performing an in-place upgrade of a virtual machine VM instance that is running an earlier version of Windows Server can be a pragmatic way to modernize your infrastructure and to mitigate the risks of approaching the end of the support lifecycle of Windows Server versions.
Alternatives to consider Before you decide to use an in-place upgrade to migrate to a newer version of Windows Server, be aware of the following limitations: Downtime: Depending on the configuration and software installed, the upgrade might take an hour or longer. During the upgrade, access to the VM instance is limited because: Workloads running on the VM instance are unavailable to users Remote Desktop Protocol RDP is not available There are limited ways to check the upgrade progress and the time remaining in the upgrade Risk: Depending on the configurations of your existing instances and the installed software: The upgrade can fail Some configuration options can be overridden Incompatibilities can cause your workload to malfunction on the upgraded instance Depending on the workload running on your Windows Server instance, you can reduce downtime and risk by pursuing different approaches.
You have a VM instance that is running a multitude of workloads Consider migrating these workloads to separate VM instances so that each VM instance runs only a single workload. Even if you can’t migrate all workloads, reducing the number of workloads running on a single VM instance can help reduce risks during an in-place upgrade. Product keys A Windows Server product key is valid for only a specific version; when you perform an upgrade to a later version of Windows Server, you must supply a new product key.
There are two primary scenarios: You are upgrading a VM instance that is based on a public operating system image provided by Google: In this scenario, you must use the predefined KMS client setup keys for the version of Windows Server that you are upgrading to. Installation media To perform the upgrade, you need an installation media.
Note that the above registry hack will change not only CTCP, but other related parameters as well, here is some additional info:. TCP chimney offload enables Windows to offload all TCP processing for a connection to a network adapter with proper driver support. Offloads are initiated on a per-connection basis and reduce networking-related CPU overhead, theoretically enabling better overall system performance by freeing up CPU time for other tasks.
It is a global setting that has to be enabled for many of the other offloads to work. Enabling this setting had some negative effects in the past because of buggy network adapter drivers, however its implementation has gotten much better with time. It is useful for CPU-bound client computers and very fast broadband connections, not recommended in some server environments. Possible states of this setting are as follows: automatic – offloads if the connection is 10 GbE, has a RTT default – this setting restores chimney offload to the system default.
One should be more careful using offloading in server environments, as there have been some reports of issues with TCP Chimney Offload and SQL servers under heavy load, affecting both application concurrency and throughput. Setting Chimney Offload to disabled is recommended for VMWare servers, and the setting is now considered deprecated by Microsoft. In essence, it provides the ability to more efficiently move network data by minimizing CPU usage. Default: disabled Recommended: leave alone, don’t bother setting not supported in Windows 8 and later, according to MS.
The objective of DCA is to reduce memory latency and the memory bandwidth requirement in high bandwidth Gigabit environments. Not present in Windows 10 Creators’ update. For more information on customizing the command, refer to this Technet article. To pick a single adapter and only modify its checksum offload state, find installed adapters using this cmdlet: Get-NetAdapter. The receive-side scaling setting enables parallelized processing of received packets on multiple processors, while avoiding packet reordering.
It avoids packet reordering by separating packets into “flows”, and using a single processor for processing all the packets for a given flow.
Packets are separated into flows by computing a hash value based on specific fields in each packet, and the resulting hash values are used to select a processor for processing the flow. This approach ensures that all packets belonging to a given TCP connection will be queued to the same processor, in the same order that they were received by the network adapter.
Notes: Needs Checksum Offload to be enabled. Only supported by some network adapters. Receive Segment Coalescing RCS is able to collect packets that are received during the same interrupt cycle and put them together so that they can be more efficiently delivered to the network stack. This can significantly increase the amount of traffic that can be handled without severely impacting the CPU.
Possible states: enabled, disabled, default Default state: enabled in Windows 10, disabled in some older versions. Recommended: disabled for lower latency and gaming, or when using Wi-Fi adapters. Enable for slightly higher throughput when lower CPU utilization is important. Also see our gaming tweaks article. This setting defines the grouping of network packets in general, to limit the number of receive interrupt and reduce the amount of required processing. This should be left enabled for pure throughput and efficiency, disabled for gaming and where lower latency is desired at the expense of a bit higher CPU utilization, and a bit more multicast traffic.
Possible states: enabled, disabled, default Default state under Windows enabled Recommended: disabled for gaming and slightly lower latency at the expense of higher CPU usage and more multicast traffic, and when using Wi-Fi adapters , enabled for pure throughput when lower CPU utilization is important To check in Powershell: Get-NetOffloadGlobalSetting.
This setting enables Large Send Offload. When enabled, the network adapter hardware is used to complete data segmentation, theoretically faster than operating system software. Theoretically, this feature may improve transmission performance, and reduce CPU load.
The problem with this setting is buggy implementation on many levels, including Network Adapter Drivers. Intel and Broadcom drivers are known to have this enabled by default, and may have many issues with it. It should only be enabled with the newest Gigabit NICs with recent drivers. Because of the issues mentioned above, we recommend disabling LSO at both the Network Adapter properties, and at the OS level with the setting below. Be careful with this setting, test before using in production.
Notes: Default state is network adapter dependent. Needs Checksum Offload to be enabled to work. LSO is another buffer that may impact latency, it is not recommended for interactive connections and gaming.
It is aimed to decrease retransmissions. In essence, ECN assumes that the cause of any packet loss is router congestion. It allows routers experiencing congestion to mark packets and allow clients to automatically lower their transfer rate to prevent further packet loss. The receiver echoes the congestion indication to the sender, which must react as though a packet drop were detected.
Possible settings are: enabled, disabled, default restores the state to the system default. Default state: disabled. May be worth trying “enabled” for gaming with unstable connections. Its effect on bulk throughput with large TCP Window are less clear. Currently, we do not recommend enabling this setting, as reportedly it has negative impact on throughput with some residential US ISPs. EA multiplayer games that require a profile logon do not support ECN as well you will not be able to logon.
However, it can also reduce latency in some games with ECN-capable routers in the presence of packet loss dropped packets. The problem with timestamps is that they add 12 bytes to the byte TCP header of each packet, so turning them on causes considerable overhead. Possible states: enabled,disabled,default Default state: disabled Recommended: disabled.
Retransmit timeout RTO determines how many milliseconds of unacknowledged data it takes before the connection is aborted. Table of contents. Note Although you can install an instance of SQL Server on a computer that is running IIS, this is typically done only for small web sites that have a single server computer.

The premium offering, SQL Server Enterprise edition delivers comprehensive high-end datacenter capabilities with blazing-fast performance, unlimited virtualization, and end-to-end business intelligence – enabling high service levels for mission-critical workloads and end-user access to data insights. SQL Server Standard edition delivers basic data management and business intelligence database for departments and small organizations to run their applications and supports common development tools for on-premise and cloud – enabling effective database management with minimal IT resources.
SQL Server Web edition is a low total-cost-of-ownership option for Web hosters and Web VAPs to provide scalability, affordability, and manageability capabilities for small to large-scale Web properties.
It includes all the functionality of Enterprise edition, but is licensed for use as a development and test system, not as a production server. Express edition is the entry-level, free database and is ideal for learning and building desktop and small server data-driven applications. It is the best choice for independent software vendors, developers, and hobbyists building client applications. Processors and memory devices are modeled as Plug and Play devices to allow hot-plugging of these devices.
Windows Server includes a variation of installation called Server Core. Server Core is a significantly scaled-back installation where no Windows Explorer shell is installed. It also lacks Internet Explorer , and many other non-essential features. All configuration and maintenance is done entirely through command-line interface windows, or by connecting to the machine remotely using Microsoft Management Console MMC.
Notepad and some Control Panel applets, such as Regional Settings, are available. Server Core can also be used to create a cluster with high availability using failover clustering or network load balancing. Windows Server offers high availability to services and applications through Failover Clustering.
Most server features and roles can be kept running with little to no downtime. In Windows Server , the way clusters are qualified changed significantly with the introduction of the cluster validation wizard.
With the cluster validation wizard, an administrator can run a set of focused tests on a collection of servers that are intended to use as nodes in a cluster.
This cluster validation process tests the underlying hardware and software directly, and individually, to obtain an accurate assessment of how well failover clustering can be supported on a given configuration. Hyper-V is hypervisor -based virtualization software, forming a core part of Microsoft’s virtualization strategy. It virtualizes servers on an operating system’s kernel layer.
It can be thought of as partitioning a single physical server into multiple small computational partitions. Hyper-V includes the ability to act as a Xen virtualization hypervisor host allowing Xen-enabled guest operating systems to run virtualized. Also, a standalone variant of Hyper-V exists; this variant supports only x architecture.
It provides resource management and can be used to control the amount of resources a process or a user can use based on business priorities. Process Matching Criteria , which is defined by the name, type or owner of the process, enforces restrictions on the resource usage by a process that matches the criteria. CPU time, bandwidth that it can use, number of processors it can be run on, and allocated to a process can be restricted.
Restrictions can be set to be imposed only on certain dates as well. Server Manager is a new roles-based management tool for Windows Server Server Manager is an improvement of the Configure my server dialog that launches by default on Windows Server machines. However, rather than serve only as a starting point to configuring new roles, Server Manager gathers together all of the operations users would want to conduct on the server, such as, getting a remote deployment method set up, adding more server roles etc.
Support for the RTM version of Windows Server ended on July 12, , [3] [4] and users will not be able to receive further security updates for the operating system. As a component of Windows Vista, Windows Server will continue to be supported with security updates, lasting until January 14, , the same respective end-of-life dates of Windows 7.
Microsoft planned to end support for Windows Server on January 12, However, in order to give customers more time to migrate to newer Windows versions, particularly in developing or emerging markets, Microsoft decided to extend support until January 14, Windows Server can be upgraded to Windows Server R2 on bit systems only.
Most editions of Windows Server are available in x and IA variants. As such, it is not optimized for use as a file server or media server. Windows Server is the last bit Windows server operating system.
The Microsoft Imagine program, known as DreamSpark at the time, used to provide verified students with the bit variant of Windows Server Standard Edition, but the version has since then been removed.
However, they still provide the R2 release. Windows Server Foundation Released on May 21, Windows Server shares most of its updates with Windows Vista due to being based on that operating system’s codebase.
A workaround was found that allowed the installation of updates for Windows Server on Windows Vista, [40] adding three years of security updates to that operating system Support for Windows Vista ended on April 11, , [41] while support for Windows Server ended on January 14, Due to the operating system being based on the same codebase as Windows Vista and being released on the same day as the initial release of Windows Vista Service Pack 1 , the RTM release of Windows Server already includes the updates and fixes of Service Pack 1.
Service Pack 2 was initially announced on October 24, [42] and released on May 26, Service Pack 2 added new features, such as Windows Search 4. Windows Server specifically received the final release of Hyper-V 1.
