This article will give you all the information you need to know about the Infor OS decommission, as well as what you will need to migrate from Infor OS on-prem to Infor LTR on-prem.
What is happening?
Infor OS and Infor OS Lite on-premises are moving to sustaining maintenance on March 31, 2025. Sustaining maintenance means that there will be no new patches, updates, or fixes for Infor OS. The pre-existing patches and documentation will remain available.
Reason for the Change
On-premises Infor OS installations are currently running on outdated software components, including outdated versions of Windows, Java, SQL Server, and .Net Framework. The new product, Infor LTR, will allow all for all of these components to be upgrade to newer and more secure versions.
What are my Options?
On-premises customers have three options for handling this change:
- Purchase a new MT Infor OS license tier (SaaS)
- This is a cloud offering from Infor that would create a hybrid environment for clients. Infor OS would run in the cloud, and can still be used for SSO authentication, and your remaining Infor applications could stay on-prem.
- Upgrade to Infor LTR
- Take no action and continue to use Infor OS (this contains risks)
What are the Risks of Staying on Infor OS?
Keeping Infor OS can cause your organization to miss out on important security updates. It also would require your organization to maintain an application on outdated technology, which can be a security risk.
What is Infor LTR?
Infor LTR is a core technology runtime service, that is a “wrapper” for Infor applications. It serves as a single hub where users can log into one URL and then access all their Infor applications from a menu. Infor LTR will be supported until at least 2029.
How to Upgrade
To upgrade from Infor OS to Infor LTR, it is possible to do an in-place upgrade procedure. For a one-step upgrade, you must currently be on Infor OS 2021.12 or higher. If you’re not on a compatible version of Infor OS, you’ll need to first upgrade Infor OS to one of those versions, and then you can upgrade to Infor LTR.
The upgrade process has the exact same look & feel, and the same installer as Infor OS, so if you have previously done an Infor OS upgrade, you will not have any learning curve.
Server & Compatibility Specifications
Before starting any kind of Infor upgrade, please first read the installer document for the exact specifications. As of the writing of this article, these are the specifications for Infor LTR:
- Microsoft SQL Server 2022, 2019, or 2017
- Windows 2022 or 2019
- .NET Framework 4.8
- AWS Corretto JDK 17 (Infor LTR requires a very specific minor version, so be sure to check your documentation before downloading)
- Minimum Hardware
- 4 CPU Cores*
- 32 GB of RAM*
- Install drive of 50GB+
- Data/content drive of 300GB+
*NOTE: These are minimum hardware recommendations. If you are going to use Infor LTR for SSO authentication, it is recommended that you increase the CPU cores and RAM.
Using Infor LTR with Web Applications
Infor LTR offers the same Infor web application utilities as Infor OS. You can set up menu widgets for applications such as Lawson, LBI, and MSCM. You can still use the direct URL to access these applications. Infor LTR is not required the access your Infor web apps, but it is required for compliance with your Infor licensing. Infor LTR is required if you want your Infor applications to authenticate using an identity provider other than ADFS.
Here are some basic screenshots of setting up and application in Infor LTR:
Infor LTR as STS
Infor LTR can be used as the SSO authentication application for all your Infor web applications. You can authenticate using multiple different identity providers (IdP). For instance, you can configure Infor LTR to authenticate with Azure AD, MS Entra, AD FS, or Okta.
Where do I get Infor LTR?
