Bridge to the Future: Integrating SAS 9.4M8 with Cloud and Viya Environments Key Technical Sections to Include 1. Introduction: The M8 Milestone Release Context:

SAS 9.4M8 was released to address the modern security landscape, specifically moving away from older dependencies Support Lifecycle: sas 9.4m8

Standard support for the M8 platform is currently slated to last until February 1, 2028 Primary Objective:

Emphasize that M8 is designed for security compliance (e.g., updating Java and internal components) and better integration with 2. Major Technical Enhancements Database Updates: A critical feature of M8 is the requirement to upgrade to PostgreSQL 14.x to ensure ongoing security fixes Accessibility Options: New system options like ACCESSIBLEGRAPH ACCESSIBLEPDF ACCESSIBLETABLE allow for the creation of accessible ODS output by default Unicode Support:

M8 improves how searchable PDF files are generated within Unicode sessions, solving previous character-spacing bugs System Logging: LIMITPROCNOTES

option was officially added to M8 in December 2023 to help manage log volume 3. Deployment and Infrastructure SAS 9.4 Maintenance 8 is available

5. CASL (SAS’s Modern Scripting Language)

M8 improves CASL for data processing directly in CAS without passing data to SAS. If you are looking to write a technical

Helpful Code Example – CASL inside a DATA step:

proc cas;
   session mySession;
table.loadTable /
caslib="casuser"
path="large_data.sashdat"
importOptions=fileType="sashdat";
simple.groupBy /
table=name="large_data", groupBy="region"
aggregator="mean"
aggVars="revenue"
casOut=name="summary", replace=TRUE;
quit;

Conclusion: Should You Upgrade to SAS 9.4M8?

| Upgrade if... | Stay on M7 or consider Viya if... | |-------------------|----------------------------------------| | You need TLS 1.3 or modern security compliance | Your organization is actively migrating to Viya within 12 months | | Your users want SAS Studio 5.2 and Git integration | You rely on deprecated SAS/GRAPH Java/ActiveX graphics | | You use PROC SQL or SORT on large data and want free speed gains | You have a complex custom web application built on SAS 9.4M7’s specific APIs | | You produce regulatory PDF/A reports | Your hardware cannot meet M8’s minimum requirements (e.g., outdated RHEL 6) | Conclusion: Should You Upgrade to SAS 9

For the majority of enterprise SAS 9.4 customers, SAS 9.4M8 is the recommended, stable, secure, and final evolution of the classic SAS platform. It buys you another 3–5 years of robust analytics without forcing a cloud migration. However, treat it as your last upgrade on this architecture—and begin your strategic plan for SAS Viya.

Part 1: What is a SAS Maintenance Release? Understanding the Versioning

Before detailing M8, it is crucial to understand SAS’s versioning strategy. SAS 9.4 was originally released in July 2013. Since then, SAS has issued multiple maintenance releases:

• SAS 9.4M1 (2014) – Introduced UTF-8 support and Hadoop integration.
• SAS 9.4M2 (2014) – Added the CAS (Cloud Analytic Services) client.
• SAS 9.4M3 (2015) – Enhanced high-performance procedures.
• SAS 9.4M4 (2016) – Brought the SAS Viya 3.1 launchpad.
• SAS 9.4M5 (2017) – Introduced the SAS® Event Stream Processing engine.
• SAS 9.4M6 (2018) – Focused on security (TLS 1.2) and accessibility.
• SAS 9.4M7 (2020) – Added the SAS Job Execution Web Application.
• SAS 9.4M8 (Late 2022) – The current stable pinnacle.

Each M-release is cumulative. Installing SAS 9.4M8 automatically includes all fixes and features from M1 through M7. Importantly, M8 is a full installation—you cannot “patch” from M7 to M8; it requires a new deployment or an in-place upgrade using the SAS Deployment Wizard.

4. Functions and Call Routines

• FINDFUNC function: Returns the line number where a specific text pattern appears in an external file – a lifesaver for log parsing.
• GETOPTION function: Now returns current system option values for cloud-enabled sessions.
• JSONVALUE function: Extracts a value from a JSON string without needing PROC JSON. This is huge for web API integration.

Step 3: Test in a Non-Production Environment

Spin up a clone of your SAS environment and perform a side-by-side upgrade:

1. Install M8 on a new server or separate directory (e.g., /sas/config_m8).
2. Migrate your metadata using the SAS Migration Utility.
3. Run your critical production jobs (ETLs, reports, analytics).
