Servicing channels
There have been historically three primary release channels available:
- Long-Term Servicing Channel (LTSC)
- Semi-Annual Channel (SAC)
- Annual Channel (AC)
The Windows Server Semi-Annual Channel (SAC) was retired on August 9, 2022. There will be no future SAC releases of Windows Server.
The Windows Server Annual Channel (AC) was released after the retirement of the Semi-Annual Channel (SAC). The first release of the Annual Channel (AC) was on October 24, 2023.
Long-Term Servicing Channel (LTSC)
With the Long-Term Servicing Channel, a new major version of Windows Server is released every 2-3 years. Users are entitled to 5 years of mainstream support and 5 years of extended support. The Long-Term Servicing Channel will continue to receive security and non-security updates, but it will not receive the new features and functionality.
Semi-Annual Channel (SAC)
Each release in this channel is supported for 18 months from the initial release. Most of the features introduced in the Semi-Annual Channel have been rolled up into the next Long-Term Servicing Channel release of Windows Server.
In this model, Windows Server releases were identified by the year and month of release: for example, in 2017, a release in the 9th month (September) would be identified as version 1709. Fresh releases of Windows Server in the Semi-Annual Channel occurred twice each year. The support lifecycle for each release is 18 months. Starting with fall 2020 (20H2) releases, the identification changed. Instead of a month, the release is named based on the release cycle. For example: version 20H2, for a release in the second half of the year 2020.
Annual Channel (AC)
Similar to Semi-Annual Channel (SAC), but releases occurred every 12 months.
The support lifecycle for each release is 18 months of mainstream support, plus 6 months of extended support.
Extended Security Updates (ESU)
For some releases, customers also have the option to purchase Extended Security Updates (ESU).
It includes Critical and/or Important security updates for a maximum of three years after the
product’s End of Extended Support date. Customers can also get technical support for the ESU period
as long as they also have an active support plan.
More information is available on the Microsoft Windows Server website.
You should be running one of the supported release numbers listed above in the rightmost column.

Windows client OS support period is basically 10 years from product release.
Windows Server OS had a five-year “mainstream support” and additional five-year “extended support” period.
The main difference point between mainstream support and extended support is whether or not updates are provided for non-security related issues (such as defects).

The following table shows the support status at the time of release of Windows Server 2019
Windows Server 2019 version | GA date | end of mainstream support | end of extended support |
---|---|---|---|
Windows Server 2019 | Nov-13-2018 | Sep-10-2024 | Oct-9-2029 |
※ Standard / DataCenter / Essentials all the same

Same as older Windows Server release, windows server 2019 is up to 5 years + 5 years, 10 years support.
How to get the product evaluation version is as mentioned in the following article.
As of this writing, the easiest way to use a Windows Server 2019 is using cloud instance as an evaluation version in Azure.
If you do not have an Azure account, I think that you can create a free account.

Top 9 Risks of Sticking with Windows Server 2019 After its EOL
Continuing to use Windows Server 2019 after its EOL poses several significant risks and challenges for your organization. That’s because Microsoft will stop providing regular security updates, bug fixes, and technical support. Take a look at some of the risks you might face:
1. Security Vulnerabilities
The biggest danger is exposure to security vulnerabilities. Without regular security updates, any newly discovered vulnerabilities or exploits will remain unpatched, making your server infrastructure susceptible to cyberattacks, malware infections, and data breaches.
2. Non-Compliance
Many regulatory authorities will require you to use supported and updated software to protect sensitive data in order to remain compliant. That means using an unsupported operating system like Windows Server 2019 could lead to compliance violations and legal repercussions.
3. Lack of Technical Support
After its EOL, Microsoft will no longer provide technical support for Windows Server 2019. That means you won’t have access to official assistance for troubleshooting issues, which could lead to extended downtime and operational disruptions.
4. Limited Compatibility
Software and hardware vendors focus on supporting newer operating systems. Continued use of Windows Server 2019 might cause compatibility issues with third-party applications, drivers, and hardware components, hindering your ability to run essential software and systems.
5. Decreased Performance and Reliability
Over time, using an unsupported OS might lead to performance issues, stability problems, and other technical challenges due to the lack of updates and optimizations. Newer Windows Server versions bring in improved features, performance enhancements, and security measures. You miss out on all those benefits by sticking with the unsupported Windows Server 2019.
6. Inability to Scale
If your organization is growing or your IT needs are changing, using an outdated OS might limit your ability to scale and adapt to new requirements. That’s because new applications and hardware will no longer be compatible with Windows Server 2019.
7. Loss of Vendor and Third-Party Support
When it comes to your server’s OS, you do not want to be left behind. Vendors and third-party providers will also phase out support for Windows Server 2019 as time passes, leaving you without options for assistance when you encounter issues.
8. Negative Impact on Reputation
Clients, partners, and stakeholders may view your organization as less technologically advanced or security-conscious if you continue using an unsupported OS, potentially harming your reputation.
9. Higher Maintenance Costs
While it might seem cost-effective to avoid immediate migration, the long-term costs of maintaining an unsupported OS can become significant. Custom support agreements or emergency fixes can be expensive.
Alternatives to Windows Server 2019
To avoid the abovementioned risks, you must find an alternative immediately. That means you must find a new OS compatible with your organization’s specific needs, existing applications, and hardware. It’s also essential to evaluate the features and benefits of each option so you can find the suitable alternative that aligns with your organization’s IT strategy and goals.
Thankfully, there are quite a few options available that can meet those considerations. Here are some alternatives you can check out:
1. Windows Server 2022
Transitioning to Windows Server 2022 is a viable option for businesses seeking continuity and enhanced security. This latest iteration boasts improved security features, including enhanced multi-layer protection and built-in breach resistance, fortifying your infrastructure against modern cyber threats.
2. Cloud-Based Solutions (Azure, AWS, etc.)
Embracing cloud-based solutions offers flexibility, scalability, and robust security features. Migrating to platforms like Azure or Amazon Web Services (AWS) enables seamless data management, reduces maintenance overhead, and provides access to cutting-edge technologies without the burden of managing on-premises infrastructure.
3. Linux-based Servers
For businesses seeking cost-effective and highly customizable solutions, Linux-based servers present a compelling alternative. Offering a wide array of distributions tailored to diverse needs, Linux ensures stability, security, and a vibrant open-source community for ongoing support.
12 Steps to Take When Migrating to a New Server OS
Before making the leap to a new server OS to replace your aging Windows Server, charting a detailed plan is essential. Remember, a well-thought-out and executed server migration strategy will pave the way for a seamless shift and minimize potential disruptions to your organization’s IT setup.
Here’s a rundown of critical steps to ensure a smooth migration:
Step 1: Assess Application Compatibility
First, check if all the applications and services currently running on your Windows Server 2019 are compatible with the new OS version. Some might need updates or tweaks for optimal performance on the new platform.
Step 2: Evaluate Hardware Compatibility
Ensure your existing hardware meets the requirements specified for the new Windows Server version. Upgrading or replacing hardware components might be necessary.
Step 3: Backup Data and Prepare Recovery Plans
Before tackling the upgrade, create comprehensive backups of all vital data and configurations. A reliable backup and recovery plan is crucial in case any issues arise during the migration.
Step 4: Perform a Thorough Security Audit
Conduct a detailed security audit of your current Windows Server 2019 setup. As you migrate to a new OS, sensitive data will be in transit, increasing the risk of interception. Identify and address any security vulnerabilities to ensure a secure transition. Consider conducting another audit post-migration to reevaluate security measures.
Step 5: Provide Training
If the new OS introduces significant changes in interface or features, offer training sessions to your IT staff. Ensuring familiarity with the new environment will help prevent issues like misconfiguration.
Step 6: Review Network Configurations
Check your network settings for compatibility with the new OS. Adjust configurations that conflict with new features or obsolete functions to avoid complications.
Step 7: Prepare for Downtime
Anticipate potential downtime required for the migration process. Develop a schedule to minimize disruptions during the transition.
Step 8: Test the Network Environment
Create a test environment to simulate the migration process. Identify and resolve compatibility issues with applications, services, or configurations beforehand.
Step 9: Communicate the Migration
Inform your IT team, stakeholders, and end-users about the impending changes, potential downtime, and any necessary actions.
Step 10: Document the Process
Document each step of the migration, configurations made, and encountered issues. These records will serve as valuable references for future troubleshooting.
Step 11: Craft Contingency Plans
Be prepared for unforeseen challenges by drafting contingency plans. Include rollback procedures in case of unexpected hiccups during migration.
Step 12: Seek Expert Assistance
Consider engaging IT consultants or managed service providers specializing in Windows Server migrations if your organization lacks in-house expertise. Their experience and knowledge can ensure a smooth transition.
