Upgrading MarkLogic Data Hub: Managing the Transition from DHF 4.1.x to DHF 5.2.x

Migrating from one version of software to another can be a daunting task, especially when you have a complex structure in place. If you're in the process of upgrading your MarkLogic Data Hub from DHF 4.1.x to DHF 5.2.x, you're probably wondering how to efficiently manage the transition of your existing standard ingestion and harmonization flows. In this post, we will discuss the current limitations and best practices for this upgrade, providing you with clarity and guidance for a smoother migration.

Understanding the Upgrade Challenge

The main concern when migrating to a new version of MarkLogic Data Hub is whether you can easily convert and replicate your existing flows. Many developers fear that a complete reconstruction of workflows could lead to extensive work hours, especially for those who have already invested significant time creating their 4.1.x flows.

The Key Question

Can existing DHF 4.1.x flows be automated into DHF 5.2.x equivalent ingestion and mapping steps?

The documentation for DHF 5.2.x may imply that there isn’t a straightforward automated mechanism to achieve this, leaving many users in search of a viable solution.

Current State of Migration

No Automated Migration Tool

Unfortunately, as it stands, there is no automated tool available to directly convert DHF 4.1.x flows to DHF 5.2.x. This means that the processes built in the previous version will not seamlessly transition to the new version of the Data Hub. Here are some options to consider for your upgrade:

Maintain Current Flows: You can choose to keep your existing DHF 4.1.x flows operating as they are. This allows you to avoid disruption while evaluating the benefits of the new version.

Evaluate Out-of-the-Box (OOTB) Steps: The primary incentive to upgrade to DHF 5.2.x is the introduction of out-of-the-box steps for mapping, matching, and merging. Assess how these features could enhance your processes before committing to a full migration.

Steps to Follow

If you decide to take the migration plunge, consider these steps:

Assess Your Current Flows: Analyze your existing DHF 4.1.x flows to identify which parts are critical and valuable, and whether they can benefit from DHF 5.2.x’s new features.

Test & Prototype: Create prototypes of the essential flows in DHF 5.2.x to understand how changes may impact your overall architecture and processes.

Incremental Migration: Instead of a complete overhaul, consider migrating one flow at a time. This phased approach can help reduce risks associated with migration and allow your team to adjust gradually.

Documentation & Training: Ensure that you have access to up-to-date documentation regarding DHF 5.2.x, and invest time in training your developers on the new system and its capabilities.

Feedback Loop: Keep an active feedback loop between your development team and the goals for using DHF 5.2.x, ensuring they have a voice in the migration process.

Conclusion

While the absence of a direct automated conversion from DHF 4.1.x to DHF 5.2.x may seem like a setback, it also provides an opportunity to reflect upon and improve your data processes. Take the time to weigh the new features against your existing operations. By strategically evaluating and executing the migration process, you can effectively manage the transition while minimizing disruption to your workflows.

Remember, it’s not just about changing versions; it’s about enhancing your data management capabilities.
