Retire Old Systems. Keep All the Data.

ELLKAY handles your most complex data projects, so you don't have to. From source system extraction and normalization to import and archive, we support you
through the entire data lifecycle.

THE PROBLEM

Legacy systems are costing you money every day you keep them running.

Licensing, infrastructure, support, and security exposure all add to the burden. The longer these systems remain active, the more complex and costly the eventual migration becomes.

THE SOLUTION

Decommission systems. Retain data. Reduce costs.

ELLKAY migrates historical data into a secure, HIPAA-compliant cloud archive we orchestrate end-to-end. Clinical teams access historical records via SSO from the current EHR. Finance teams keep posting payments, running down open A/R, and managing claims directly in the archive, without missing a beat. 

Our numbers

Less Overhead. No Data Loss. Faster Modernization.

ELLKAY has migrated and archived data from 480+ healthcare applications, including more than 100 acute systems and 315+ ambulatory systems - across clinical,
financial, and ERP environments.

Why Data Access Can’t Wait

How LKOasis Manages Your Data Lifecycle

Legacy systems shouldn’t keep draining your team’s time, budget, and resources. Ongoing licensing fees, aging infrastructure, security risk, and one-off access requests can make old systems expensive to maintain and difficult to retire. The challenge is moving the right data without interrupting clinical, financial, or operational workflows. That’s where ELLKAY comes in.

ELLKAY extracts data from legacy applications and runs it through a structured mapping and normalization process to reduce manual cleanup and improve data quality at scale. Once normalized, the data is loaded into a secure, searchable cloud archive. With SSO integration into the existing EHR, clinicians and staff can access the information they need in one click from the workflows they already use.

The archive is more than a place to store data. It becomes a working system that supports financial, clinical, and operational needs. Financial archives can support active A/R runout, payment posting, adjustments, claims processing, collections reporting, and work queues. Clinical archives can support HIM Release of Information workflows, smart search across historical records, and on-demand reporting. Your teams stay productive, and your legacy systems can finally go dark.

Key Benefits

Organizational Impact

LKOasis eliminates the operational and financial burden of maintaining legacy systems,
so your organization can invest in modernization rather than maintenance.

Decommission legacy applications and eliminate their ongoing costs. One customer reduced legacy technology costs by 60%, a [link=/success-story/customer-success-story-lehigh-valley-health-network]$13M reduction[/link], after archiving more than 100 applications with ELLKAY.

LKOasis provides a predictable, subscription-based archive cost that replaces unpredictable legacy system maintenance which simplifies IT budgeting and frees capital for strategic investments.

Historical patient records remain accessible after legacy systems are retired, with SSO integration that surfaces the archive directly in the current EHR workflow.

Clinical teams access historical records at the point of care. Finance teams continue running down A/R and responding to audits. HIM teams complete release of information workflows.

Legacy systems that are no longer actively supported represent growing cybersecurity exposure. Retiring them removes that risk, while LKOasis preserves the data those systems held for as long as compliance requires.

LKOasis supports long-term data retention across clinical, financial, and operational records, helping your organization stay audit-ready without keeping vulnerable systems running.

Why ELLKAY?

The ELLKAY Difference

ELLKAY also brings deep source system expertise: 290+ EHRs and 350+ applications across clinical, financial, ERP, lab, and specialty environments.

Breadth Across All Data Types

One archiving partner for clinical, financial, ERP, laboratory, pathology, blood bank, and specialty data. Instead of managing multiple archive vendors for different system types, organizations work with ELLKAY across  all of them.

Active Archive, Not Just Storage

LKOasis is a working system your teams use after the legacy system is retired, not a compliance vault they hope they never need.

Managed Migration, Not Just Software

You shouldn't need to build an internal data migration practice just to retire a legacy system. ELLKAY's project teams have managed large-scale migration and decommissioning programs across complex health system environments and they bring that experience to every engagement.
