MarkLogic Upgrade

The clock is ticking. MarkLogic version 8 is obsolete. Version 9 was retired in March 2024. Version 10 reaches end-of-life in March 2026. If you're running these versions, you're operating without security patches, bug fixes, or vendor support. It's time to act.

# The Urgency of Upgrading

Organizations should upgrade to at least MarkLogic 11.3 LTS (Long-Term Support) for stability and extended support through 2028, or embrace the innovative features of MarkLogic 12 and beyond. The choice depends on your needs, but staying on unsupported versions exposes your business to unnecessary risk.

# The Complexity Gap

Here's the reality: upgrading is rarely straightforward when you've fallen behind. The bigger the version gap, the greater the complexity. Each major version introduces changes—new features, deprecated functionality, and breaking changes. But that's only part of the challenge.

# The Dependency Matrix Challenge

MarkLogic doesn't exist in isolation. Your ecosystem may include:

• Data Hub Framework (DHF) - different versions require different MarkLogic versions
• Java Client API - must align with server capabilities
• ml-gradle - deployment automation with version-specific requirements
• ml-app-deployer - configuration management dependencies
• Apache NiFi - integration layer compatibility
• Gradle itself - build tool version requirements
• Java/JDK versions - runtime environment considerations

Navigating the dependency matrix between all these interconnected tools becomes exponentially more complex with larger version gaps. What works with MarkLogic 9 may break entirely in version 11. A DHF upgrade might require updating Gradle, which impacts ml-gradle, which affects deployment scripts—and suddenly what seemed like a simple database upgrade becomes a multi-faceted technical challenge.

# Our Expertise Ensures Success

We've navigated these complexities countless times. We understand the ins-and-outs of version nuances, compatibility requirements, and upgrade paths that aren't always documented. We've even bridged gaps in vendor documentation to help clients successfully upgrade when no clear path existed.

We work with you to:

• Assess your current environment and version landscape
• Plan a viable upgrade roadmap addressing all dependencies
• Test the upgrade path in controlled environments
• Execute the upgrade with minimal disruption
• Validate functionality and performance post-upgrade
