Choosing the Right LIMS Migration Strategy for Your Lab

‍

Your lab is ready to replace its existing Laboratory Information Management System (LIMS). You have done your due diligence through research into vendors, solutions and features and decided which direction to take. However, there is one last critical decision to make in the implementation process – which migration approach will you use?  

The goal for migration is to ensure that the transition is smooth, with minimal disruption to laboratory operations. This includes having a well-planned process outlined in advance of beginning the migration. LIMS migrations can be a challenging process; however, there are key strategies that laboratories can utilize to ensure success and minimize risk.

Three well-known approaches when migrating to new software include: Parallel, Incremental, and Big Bang. Each approach has its advantages and challenges, and the choice depends on factors such as the size of the lab, the complexity of the data, and the resources available. Below is an overview of these approaches:

Parallel Testing:

With Parallel Testing, the new LIMS runs simultaneously alongside the old system for a defined period, minimally two (2) weeks. During this time, the systems operate concurrently, with data logged into both systems. Additionally, this allows time for the new LIMS to be fully validated and for users to become adjusted to the new processes. The goal of Parallel Testing is to produce an identical output from each system.

ADVANTAGES:

• Risk Mitigation: Running both systems in parallel allows for thorough comparison and validation of data and processes, reducing the risk of data loss or errors. In the event of any significant issues with the new system, the old system is still in place to provide continuity for the lab operations. Parallel testing also ensures that the team feels confident in the system’s output based on test and user case scenario results.

• Training and Adaptation: Parallel Testing provides users with the opportunity to become accustomed to the new system, while still having the old system as a fallback.

• Operational Continuity: There is minimal disruption to laboratory operations as both systems are available.

CHALLENGES:

• Resource Intensive: Maintaining and operating two systems simultaneously requires additional resources, both in terms of personnel and infrastructure.

• Duplication of Data: Entering data into two systems can be time-consuming and increases the workload for lab personnel.

• Extended Transition Period: Parallel operations can prolong the migration period, potentially delaying the project.

• Increased Cost: Maintaining two environments is less cost effective.

• Technical Complexity: The integration capabilities (i.e. instruments, enterprise applications) required to maintain parallel coordination of data can be significant.

Incremental Approach:

An Incremental approach focuses on migrating one dataset at a time or addressing specific components of the laboratory operation individually, rather than all at once, much like wading into the ocean.

‍An example Incremental scenario:

Phase I: System (LIMS)configuration, including set-up of Sample Types, Methods, Calculations, Preparation Steps, QC Types/Limits, Projects, Schedules, Data Qualifiers/Flags, Workflows, and other relevant Static Data items. System Administrator Training.

Phase II: Instrument integration, associated verification testing and validation, and end-user training that must occur before going live.

Phase III: Enterprise integration with systems such as SAP, GIS, SCADA, manufacturing solutions and/or accounting packages. Final cut-over.

ADVANTAGES:

• Reduced Risk: Migrating in smaller increments allows for careful monitoring and troubleshooting of each segment, reducing the risk of major failures. Provides the flexibility to roll back in the event of unexpected issues.

• Flexibility: The incremental approach offers flexibility in managing unforeseen issues, making it easier to pause and address problems without affecting the entire system.

• Focused Training: Training can be conducted in phases, making it easier for users to learn and adapt to the new system.

CHALLENGES:

• Prolonged Duration: The overall migration process can take longer due to the phased approach, potentially leading to extended periods of adjustment and delayed time to value.

• Complexity: Challenges with an incremental launch strategy are related to the complexity of the LIMS (configuration and feature/function breakdown), data, and the laboratory’s business processes. It requires extensive planning and coordination to cross the phases.

• Consistency Issues: Maintaining data consistency and integrity across both systems can be challenging during the transition period.

Big Bang Approach:

The Big Bang data migration concept is simple – switch over from the old LIMS to the new one in a single, comprehensive move, like diving into a pool headfirst. The organization picks a date for the switch to take place, and all data and processes are transferred at once. The old system is decommissioned immediately after the new system goes live. Typically, during these types of deployments, people are working around the clock.  

ADVANTAGES:

• Quick Transition: All migration tasks are greatly compressed, and any issues that are uncovered that did not appear during testing must be immediately resolved.

• Cost-Effective: This approach can be more cost-effective as it eliminates the need to maintain and operate two systems concurrently.

• Immediate Benefits: Users and management can immediately start realizing the benefits of the new system.

CHALLENGES:

• High Risk: The all-at-once nature of Big Bang Migration makes it the riskiest approach, as any issues during the migration can lead to significant disruptions. This approach is typically used in emergency migrations, when the current system is abruptly unavailable, and a new system must quickly be deployed.

• Intensive Planning: Requires meticulous planning, preparation, and testing to ensure a successful transition.

• Training Challenges: Users must be fully trained and proficient with the new system before the cutover, which can be demanding in a short timeframe.

Conclusion:

In conclusion, the Parallel Migration approach offers a safer but resource-intensive option, Incremental Migration provides a balanced and flexible approach with a longer timeline, and Big Bang Migration promises a rapid transition but comes with higher risks. Proper planning, thorough testing, and effective training are crucial to the success of any migration strategy. In deciding which approach is best, you must determine your goals and assess the resources required. A LIMS professional can help.
