TOGAF 10 vs 9.2: Key Differences and What Changed

← Back to TOGAF Hub

Everything changes. In the world of Enterprise Architecture (EA), the TOGAF Standard has been the "Gold Standard" for over 25 years. But the way we build companies has changed. We are no longer in a world of Waterfall development and monolithic data centers. We are in a world of Agile, Cloud, and AI.

To keep up, The Open Group has launched the TOGAF Standard, 10th Edition. In this final post of our 35-part masterclass, we’ll look at what has changed, what stayed the same, and what it means for your career.

TOGAF 10 vs 9.2: The Key Difference in One Sentence

TOGAF 9.2 is a single, comprehensive document; TOGAF 10 is a modular library where you only use the guides relevant to your sector, project type, and delivery approach — making the same framework far easier to apply in practice.

The Biggest Shift: Monolith to Modular

If you've read the TOGAF 9.2 manual, you know it’s a massive, 500-page "monolithic" document. It’s hard to navigate and even harder to customize.

TOGAF 10 completely changes this. It is now a Modular library, split into two main parts:

1. The Fundamental Content

This contains the "enduring" part of the framework. It includes the ADM cycle, the core principles, and the governance frameworks that don't change regardless of your sector. This is the "soul" of TOGAF.

2. The TOGAF Series Guides

This is where the "flavor" of the framework lives. Instead of one big book, you have dozens of smaller, highly specific Series Guides. There are guides for:

Agile Architecture
Customer Experience
Digital Transformation
Microservices
Government & Public Sector

This means you only need to read and apply the modules that are relevant to your specific industry and project.

Support for Modern Delivery (Agile & DevOps)

In TOGAF 9.2, "Agile" was mentioned, but it wasn't a core part of the process. In TOGAF 10, Agile and DevOps are first-class citizens.

The framework now provides explicit guidance on how to run "Iterative ADM" cycles that sync with Agile Sprint cycles. It also moves from "Rigid Governance" to "Adaptive Governance," which focuses on continuous compliance rather than waiting for a formal board meeting every 3 months.

Should You Transition to TOGAF 10?

If you are already TOGAF 9.2 Certified, don't panic! The core of the framework (the ADM, the Content Metamodel, etc.) remains identical in both versions. Your 9.2 certification is still valid and respected.

However, we recommend all architects familiarize themselves with the Series Guides. This is where the most modern, practical advice lives. Whether you are leading a Cloud migration or a Digital Transformation, the TOGAF 10 library has a guide specifically designed for you.

TOGAF 10 Certification: What Changed?

The Open Group has updated its certification programme to reflect TOGAF 10. Key points for practitioners:

TOGAF 9.2 certifications remain valid — there is no forced expiration date for existing credentials.
A new TOGAF 10 Foundation and TOGAF 10 Practitioner certification track has been introduced alongside the legacy 9.2 programme.
Candidates taking the new TOGAF 10 exams will be tested on the modular structure and the Series Guides, in addition to the ADM core.

For a detailed breakdown of the exam levels and which is right for your career stage, see our TOGAF certification levels guide.

The official TOGAF 10 standard and Series Guides are published by The Open Group. The complete standard is available to members and can be previewed freely on their site.

Practical Recommendations for 2026

If you are actively practising EA in 2026, here is what the TOGAF 10 shift means for you day-to-day:

Keep your 9.2 knowledge. The ADM core is unchanged. Every phase, every deliverable, every governance structure remains the same. Your investment in 9.2 study is fully transferable.
Explore the Series Guides relevant to your sector. If you work in FinTech, read the Agile Architecture and Digital Transformation guides. If you work in government, prioritize the Government & Public Sector guide.
Leverage TOGAF 10 in conversations with stakeholders. The modular pitch ("we only apply the parts relevant to your programme") makes EA far less intimidating to business stakeholders who previously saw TOGAF as bureaucratic overhead.
Pair TOGAF 10 with modern tooling. The framework is methodology-neutral — it works equally well with ArchiMate modelling (see our ArchiMate modeling guide) and cloud-native deployment patterns.

Key Takeaways: TOGAF 10 vs 9.2

Same core, new structure: The ADM, Content Metamodel, Architecture Repository, and governance structures are identical in both versions. A TOGAF 9.2 certified professional already knows the fundamentals of TOGAF 10.
Modular is the major change: TOGAF 10 replaces the single monolithic document with a Fundamental Content document plus a growing library of Series Guides. You only study and apply the guides relevant to your context.
Agile and DevOps are first-class: TOGAF 10 explicitly addresses Agile ADM cycles, adaptive governance, and iterative delivery in ways that TOGAF 9.2 only hinted at.
Existing credentials remain valid: The Open Group has confirmed TOGAF 9.2 certifications are not time-limited. You can choose to pursue a TOGAF 10 certification separately.
The Series Guides are the investment: The most practical value in TOGAF 10 for working architects is in the Series Guides. Each covers a specific domain — cloud, Agile, digital transformation, microservices, government — with actionable guidance grounded in the ADM.
TOGAF 10 makes the business case easier: The modular pitch ("we apply only what is relevant") is far easier to sell to skeptical business stakeholders than presenting a 500-page document as the governance bible.
Learn both, apply contextually: Use TOGAF 9.2 knowledge for exam preparation and foundational understanding. Use TOGAF 10 Series Guides for practical project delivery. The full TOGAF 10 specification is available from The Open Group's official publication site.

Final Thoughts: The End of the Masterclass

This concludes our 35-part journey through the world of Enterprise Architecture. We have traveled from the basics of the ADM wheel to the complexities of security, sustainability, and the future of the standard.

Enterprise Architecture is not just a set of diagrams; it is the Strategic Engine of any modern business. By mastering the TOGAF framework, you have gained the tools to lead your organization through even the most complex transformations.

Thank you for following along. Now, it’s time to go out there and build something extraordinary!

Common Questions About TOGAF 10 vs 9.2

Does TOGAF 9.2 certification still count if TOGAF 10 is the current standard? Yes. TOGAF 9.2 certifications remain valid and recognised by The Open Group. The certification programme migrated to TOGAF 10 content, but holders of Foundation and Certified credentials under 9.2 do not need to recertify immediately. Many organisations will continue to reference 9.2 documentation for years as their internal frameworks were designed against it.

What is the most significant structural change between 9.2 and TOGAF 10? TOGAF 10 reorganised the standard into two clearly separated parts: the Fundamental Content (the stable ADM and core concepts that change infrequently) and the Guidelines and Techniques (practical guidance that can be updated more regularly without versioning the entire standard). This modular structure was absent in 9.2, where all content was presented as a single monolithic document.

Is the ADM itself different in TOGAF 10? The core ADM phases (Preliminary, A through H, Requirements Management) are unchanged. TOGAF 10 added more explicit guidance on tailoring the ADM for different contexts — Agile delivery, security architecture, digital transformation — and clarified iteration patterns. The phase names, inputs, outputs, and objectives remained consistent with 9.2, ensuring backwards compatibility with 9.2-based enterprise architecture programmes.

Which version should I study for the certification exam? The Open Group's certification exams now test TOGAF 10 content. Study materials published before 2022 cover TOGAF 9.2. For new candidates, use TOGAF 10 study guides and the current Open Group official documentation at opengroup.org/togaf. The core concepts tested at Foundation level are largely the same across both versions.

Frequently Asked Questions

Why did The Open Group release TOGAF 10 instead of TOGAF 9.3? The jump to a major version number (10) signals a significant structural reorganisation rather than incremental content updates. The separation into Fundamental Content and Guidelines and Techniques changes how the standard is maintained and extended — future updates to guidance can be published without incrementing the entire standard version. The Open Group explained this versioning rationale in the TOGAF 10 release announcement.

What new topics does TOGAF 10 cover that 9.2 did not address? TOGAF 10 added dedicated guidance on: digital transformation architecture, Agile and DevOps integration with the ADM, business architecture as a standalone discipline, and the use of TOGAF alongside ArchiMate 3.1 for modelling. It also expanded coverage of the Architecture Repository and strengthened alignment with The Open Group's broader standards portfolio, including the IT4IT standard for managing the IT function.

Where can I access the official TOGAF 10 standard? The full TOGAF Standard, 10th Edition is available from The Open Group TOGAF page. Members of The Open Group can access the standard online. Non-members can purchase it or access a free registration-based version. The Open Group also publishes official study guides for both Foundation and Certified levels through authorised training providers listed on their website.
