For SAS customers, innovation and continuity are not an either-or choice—but neither does a support policy promise that every older program, dependency, or workflow will work unchanged forever. SAS continues to support defined SAS 9 releases while positioning Viya as the main home for new innovation. The practical question is whether the exact release and stack your team relies on are supported, and how well a transition fits your workloads.
What SAS 9 support does—and does not—promise
SAS lists SAS 9.4M9 as generally available in June 2025, with standard support through July 1, 2030. SAS 9.4M8 is listed with standard support through February 1, 2028. These are release-specific dates, not a guarantee of indefinite support for every SAS 9 product or installation. Check the current SAS release support information and any product-specific terms when planning an upgrade.
SAS recommends using current releases, maintenance releases, and security hot fixes. It also notes that applying some fixes may be impractical or impossible when they create compatibility risks or unwanted side effects. That makes maintenance a risk decision as well as a calendar decision: teams need to weigh the value of a fix against its effects on validated workloads.
Compatibility depends on the whole stack
A SAS application does not run in isolation. Its operating system, database drivers, third-party software, and other dependencies can affect whether an installation is supported. SAS describes a general policy of supporting one or more baseline major versions of third-party products and subsequent minor updates. A major-version change may need separate evaluation, and exceptions can apply. This is scoped support—not a blanket promise that every version combination will work.

Before changing a component, verify the specific SAS release and the relevant dependency versions against the applicable support information. A third-party product that is compatible with one SAS release may not be covered in the same way with another.
Can you keep SAS 9 workflows while moving toward Viya?
SAS says Enterprise Guide 8.4 can connect to SAS Viya 4. That connection can give teams a familiar client for projects and code workflows as they adopt Viya. It does not, by itself, establish that every Enterprise Guide project, procedure, or dependency will behave identically in the new environment. Consult current product documentation for feature and release constraints, then test representative work before changing production workflows.
Chris Hemedinger, SAS Director of User Engagement, says Viya has monthly releases and is where most new innovation takes place. That is SAS’s description of its product strategy, not an independent comparison of the platforms. SAS also says it continues to invest in SAS 9 and describes customer transitions as happening over time; customers should use the support terms for their own release to understand what that means operationally.

| Path | What to verify | Main planning question |
|---|---|---|
| Stay on the current SAS 9 release | Its standard or limited support window, product-specific exceptions, and dependency coverage. | Does the supported window meet your operational and security requirements? |
| Upgrade within SAS 9 | The target maintenance release, operating-system and third-party support, and effects on validated code. | Can the team test the change and manage any compatibility or side-effect risks? |
| Transition toward Viya | Target-environment support, Enterprise Guide connectivity, and project and code behavior in your workload. | Which workflows need adaptation, and what migration effort and operational risk do tests reveal? |
The available support and connectivity information does not provide a complete workload-compatibility matrix or migration-cost estimate. Those answers depend on the products, dependencies, and workflows in your environment.

Quick Recap
Rank #4
A practical pre-change checklist
- Inventory the environment. Record SAS product and maintenance releases, operating systems, databases, drivers, third-party components, and the workflows that matter most.
- Confirm exact support coverage. Check each release and dependency against current SAS support information; do not infer coverage from a major-version label alone.
- Protect the current state. Back up projects, configuration, and other materials needed to restore or compare the existing environment.
- Test representative work. Include critical code and projects, connections, scheduled processes, and outputs in a non-production evaluation of the intended upgrade or Viya path.
- Set a transition plan from evidence. Identify which workflows can move as they are, which require changes, and what timing and risk are acceptable for your organization.
