A LIMS Migration Blueprint: Transitioning a High-Throughput Genomics Lab from Legacy LabVantage to Cloud-Native QBench

When a high-throughput molecular diagnostics lab spins out of a larger life-sciences company, it faces a sharp choice: copy the heavy, self-hosted systems it is leaving, or stand up a cloud-native LIMS that fits a smaller team.

A specialized molecular genomics laboratory needed to stay CAP/CLIA compliant, keep delivering data to clients, and avoid interrupting clinical trial work. It also needed to do that without inheriting a large IT footprint.

Shannon Alliance, the lab’s long-standing data management team, ran a multi-phase migration from a self-hosted LabVantage and Oracle environment to QBench. The cutover had no downtime. Annual licensing and administration costs fell by a five-figure amount. Report development turnaround fell by 75%. The lab finished on a validated cloud architecture it can keep operating itself.

This is the blueprint for how that migration was evaluated, designed, and executed.

The challenge: enterprise scale on a lean footprint

In the legacy environment, the laboratory ran a heavily customized, self-hosted LabVantage deployment on Oracle. The system could handle complex molecular genomics and immunoassay data. It was also expensive and slow to change.

• Operating cost. Self-hosted Oracle databases and LabVantage custom code needed specialized administrators and dedicated IT support. That was unsustainable for a team of about ten people.
• Change bottlenecks. Routine workflow edits and report template changes were stuck behind administrative complexity.
• Split data custody. After the spinout, the lab first worked as a subcontractor for its former parent, then took on its own clients. It had to keep legacy pipelines running for subcontracted work while standing up clean workflows for new business.

A one-month feasibility study

Before committing to a migration, Shannon Alliance spent a month estimating the effort of two options: cloning the LabVantage instance, or moving to QBench.

QBench offers an open sandbox. We used it before committing to test the API under load: endpoint behavior, how flexible the data model was, and how payloads were handled. A sales demo is not enough. Lab directors should ask for sandbox API access during feasibility and run their own data models, integrations, and payload expectations through it.

Bridging subcontracted work to a clean cutover

Business had to continue through the transition. Shannon Alliance built an interim automated pipeline, then cut over to direct accessioning in QBench.

Subcontractor phase

1. Samples were accessioned in LabVantage.
2. An automated job on Files.com picked up the files.
3. A scheduled job created the samples in QBench through the REST API.
4. Tests and results were recorded in QBench.
5. Custom scripts formatted those results to the required data transfer agreement and appended them to the historical transfer.

After cutover

1. Direct clients are accessioned in QBench.
2. An automated pipeline produces CAP/CLIA-validated reports.
3. An automated regression suite checks that later API or configuration changes do not break those pipelines.

Historical custody stayed with the former parent, so those records were not copied into QBench. The lab started with a schema built for current and future work, without carrying the old database forward.

CAP/CLIA re-validation

Under CAP/CLIA, the laboratory that performs the test has to sign reports from its own validated system. Results could not be sent back through the legacy system just to generate the report.

Shannon Alliance rebuilt and validated the report templates in QBench and updated the related SOPs. QBench’s configuration tools made template changes much faster. Report development and modification cycles dropped by 75%.

Downstream of the API, automated regression tests watch responses and confirm that vendor updates or configuration edits do not break the data transfer pipelines.

Why QBench fit this lab

The technical fit mattered as much as the license cost.

• The REST API was mature enough for Shannon Alliance to build the bridge and the cutover pipelines quickly.
• The interface was straightforward for the technicians who had to use it every day.
• The lab’s own staff were trained to make routine workflow changes, instead of calling a LIMS administrator for each one.
• QBench ran training aimed at this lab’s stack and stayed involved across the six-month deployment.

Outcomes

A checklist for the next migration

1. Spend about 30 days comparing ongoing operating cost (licenses plus administration) with the cost of the migration itself.
2. Get sandbox API access during evaluation and test your data model and payloads before you sign.
3. If historical custody can stay with the prior owner, do not backfill it. Start from a schema that matches the work you have now.
4. Put automated tests on anything downstream of the LIMS API so a vendor update cannot silently break a pipeline.
5. Plan CAP/CLIA re-validation with the build: SOPs, report templates, and validation protocols belong on the same roadmap as the six-month deployment.

Shannon Alliance designs data architecture, API automation, and LIMS integrations for clinical and research laboratories. If you are leaving a legacy LIMS or automating the pipelines around one, book a consultation.
