Knowledge is power, but in a constantly evolving world, old knowledge can become clutter. Every organization faces the dilemma of what to do with knowledgebase (KB) articles that are no longer current, refer to deprecated features, or are simply obsolete. Is it better to meticulously archive them, keeping your KB lean and relevant, or to just leave them indefinitely, trusting that “someone, somewhere” might need that obscure piece of historical data?

There are compelling arguments for both sides. Let’s dive into the debate.

🗑️ The Case for Archiving: Keeping the KB Tidy

The primary argument for archiving or even deleting obsolete articles revolves around efficiency and trust.

• Reduce Clutter and Confusion: An overflowing knowledgebase makes it harder for users (both internal support agents and external customers) to find the correct answer. Search results get diluted with irrelevant, outdated information. This leads to longer resolution times and user frustration.“Why did the search bring up a five-year-old article about a product version we discontinued?”
• Maintain Accuracy and Trust: If a user stumbles upon an old, incorrect article and follows its steps, it erodes their trust in the entire KB. A well-maintained KB signals professionalism and reliability.
• Minimize Maintenance Overhead: Every article, even an obsolete one, is a liability. You need processes to confirm it’s truly obsolete and not just rarely used. Removing it simplifies content audits and reviews.

Archiving is generally the preferred approach for articles containing:

• Outdated Procedures: Steps that no longer work.
• Security Vulnerabilities: Information that suggests unsafe practices.
• References to Non-Existent Systems/Products: Pure historical documentation that doesn’t aid a current user.

💎 The Case for Indefinite Retention: The Value of Obscurity

While a lean KB is desirable, there’s a powerful argument for keeping older articles, especially those that contain highly specific, rare, or complex information.

• The “Obscure Use Case” Lifeline: Not all users are on the latest software or hardware. Some users (especially in enterprise or legacy environments) still run older, unsupported versions. That obscure, five-year-old article might be the only solution for a critical, low-incidence issue affecting a high-value customer.
• Forensic and Historical Value: For engineering, legal, or compliance teams, older articles provide a historical record. They can explain why a system was designed a certain way, document a past decision, or serve as evidence in a legal or technical audit.
• Training and Context: New support agents or engineers benefit from seeing the evolution of a product. Older articles provide context on how things used to work, which is invaluable when troubleshooting complex integrations or legacy migrations.

⚖️ The Balanced Solution: Smart Archiving and Flagging

The best practice isn’t an all-or-nothing approach. It’s about implementing a tiered strategy that addresses the needs of both the current user and the historical researcher.

Content Status	Recommended Action	Best For
Outdated & Potentially Harmful (e.g., security risks, invalid procedures)	Delete or Archive	General users, minimizing risk.
Outdated but Historically Relevant (e.g., legacy setup guides, “End-of-Life” product documentation)	Archive and Restrict Access	Engineers, internal support, historical review.
Outdated but STILL Accurate (e.g., obscure details that never changed)	Review and Update/Merge	All users, maximizing content reuse.

Key Best Practices:

1. Don’t Delete—Archive: Instead of permanent deletion (which risks losing that one essential piece of history), move articles to a designated “Archive” section. This removes them from public search results but keeps them accessible to internal agents who specifically need to search the historical repository.
2. Tag Everything: Add a prominent “Archived” or “Obsolete: No Longer Supported” tag to the title of the article and include a clear, bold warning banner at the top. Link the user to the current, relevant article if one exists.
3. Set an Expiry Date: Implement a regular content review cycle where every article is assigned an expiration date. When that date is reached, the content owner must decide to Update, Certify, or Archive.

Ultimately, customer success should be the guiding principle. If the article helps a current user, keep it and maintain it. If it only serves historical or forensic purposes, archive it securely out of the primary search path. This prevents clutter while preserving the hidden gems.
