Let’s Redefine EHR Data Migration 01

From Paper to Digital: A Step-by-Step Guide to EHR Transition, Data Migration, and Staff Adoption

When healthcare leaders plan to move to a new EHR (Electronic Health Record) system, they often realize that rushing the process or skipping proper planning can cause long-term problems. Important data like patient problem lists can become inaccurate, reports may no longer show the real picture, and billing teams might spend months fixing missing information.

However, with careful planning, EHR data migration can make work easier, boost staff satisfaction, and support growth, enabling new services like telehealth and better use of technology.

This guide offers a clear, step-by-step plan for clinics moving to a new EHR system. It walks through every part of the process, from understanding workflows and organizing data to transferring information, training staff, and managing daily use after launch.

What is EHR Migration?

At its core, EHR migration is the process of transferring patient and operational data from one electronic health record system to another while maintaining the integrity, accuracy, and usability of that information. Unlike a simple data copy, migration is a strategic process that touches every aspect of clinic operations:

  1. Patient Care: Ensures that clinical history, allergies, medications, diagnoses, and lab results are preserved accurately so clinicians can make safe and informed decisions.
  2. Operational Workflow: Preserves scheduling, billing, and documentation workflows, while providing an opportunity to eliminate redundant or inefficient processes.
  3. Data Integrity & Compliance: Protects against data loss, corruption, and errors that could result in regulatory non-compliance or patient safety issues.

It’s also called electronic health record migration, EHR system migration, or healthcare data migration, the terms are often used interchangeably and refer to the same goal of moving data safely, restructuring workflows if needed, and enabling the clinic to function efficiently in a new system.

A key concept to understand is that data does not exist in isolation. Each field, note, or record supports clinical, operational, and administrative actions. Therefore, EHR migration is not just about moving data, it’s about preserving meaning and usability. A diagnosis code without context, a medication without stop reasons, or a lab result without reference ranges can compromise patient safety and operational reliability.

How EHR Migration Works

EHR migration is a structured, multi-stage process. While every clinic’s journey will have unique elements, the steps generally include the following:

Step 1: Assessment and Inventory

Before touching any data, the clinic must assess what exists today. This involves:

  • Cataloging all structured data: patient demographics, appointments, medications, problem lists, lab results, billing codes, templates, and order sets.
  • Reviewing unstructured data: scanned documents, historical visit notes, paper charts, and free-text clinical notes.
  • Mapping workflows: identifying every step staff take in daily operations, including informal workarounds.
  • Noting interfaces: laboratory connections, pharmacy integrations, billing systems, patient portals, and external reporting tools.

This stage uncovers the true scope of data and workflow dependencies. Often, clinics are surprised to discover how much of their daily operation relies on informal practices. For instance:

  • A nurse might know that a hidden field drives the immunization report.
  • Front desk staff may keep notes outside the system to track authorizations.
  • Billing teams may manually adjust reports every week because the standard export is inaccurate.

Without this assessment, migration decisions are made blindly, risking data loss, workflow disruptions, and staff frustration.

Step 2: Classifying Data

Once you understand what exists, the next step in EHR system migration is deciding how each piece of data should be treated. Not all data requires the same approach. Typically, there are four categories:

  1. Direct Transfer
    • Demographics, provider lists, appointment history, and some billing identifiers can often move directly.
    • Requires careful mapping to ensure that fields align correctly; otherwise, “direct” transfer can introduce subtle errors.
  2. Transformation and Cleanup
    • Problem lists may need deduplication.
    • Lab results may require code mapping.
    • Medications may require normalization, including start/stop dates and discontinuation reasons.
    • Status fields must be converted to match the new system’s interpretation of “active,” “resolved,” and “historical.”
  3. Archiving
    • Older records, inactive charts, and closed episodes are preserved in a read-only format.
    • This keeps the operational database uncluttered while maintaining access for reference, compliance, or reporting purposes.
  4. Manual Recreation
    • Critical clinical lists, unstructured notes, or paper charts may require manual reconstruction.
    • Expensive and time-consuming but necessary for patient safety and clinical accuracy.

The decisions made in this step determine how staff will interact with the new EHR, what processes will be automated, and what must remain manual or transitional.

Step 3: Data Extraction

Once the classification is complete, data extraction begins. This step is both technical and clinical:

  • Technical aspects: Exporting data from the legacy system in a format that the new EHR can accept (CSV, HL7, FHIR, or database dump).
  • Clinical aspects: Ensuring context is preserved, diagnoses with associated notes, medications with start/stop reasons, and lab results with reference ranges.

Expert Advice/Best practice: Extract data in small batches first. Review these batches with clinicians and operational staff to verify accuracy and usability. Adjust extraction rules as needed before performing full migration.

Step 4: Verification and Quality Checks

After extraction, the next step is verification. Data may look correct in a file but may not behave as expected in the new system. Verification involves:

  1. Automated checks: Counts of patients, encounters, medications, allergies, and lab results.
  2. Spot checks: Ensure critical fields are present and correctly formatted.
  3. Clinical review: Confirm that a migrated chart tells the same story as the original, preserving clinical context.

Even if automated checks pass, clinical review is essential. A chart that “looks correct” but hides subtle inconsistencies can compromise patient safety.

Step 5: Implementation Planning

With extraction and verification complete, clinics must plan how the new system will be rolled out:

  • Full switch: All users transition on the same day. Disruptive but shorter overall transition period.
  • Phased rollout: Department-by-department or provider-by-provider migration. Reduces stress but requires running parallel systems longer.

This decision affects training, staffing, downtime planning, and patient communication.

Challenges Faced During EHR Data Migration 

However, even the most experienced healthcare teams quickly realize that EHR migration is far more than a technical task. While the previous section covered assessment, data classification, extraction, and verification, this section addresses the obstacles that can derail an electronic health record migration if not proactively managed. Understanding these challenges allows a clinic to plan realistic timelines, allocate resources wisely, and prevent costly mistakes.

1. Complexity of Data

A legacy EHR contains layers of structured and unstructured data accumulated over years:

  • Structured fields: demographics, medications, problem lists, lab results, and billing codes
  • Unstructured fields: free-text clinical notes, scanned documents, patient communications
  • Custom templates: fields or reports created to workaround system limitations

Migrating this data is not a matter of simple copying. Each field must be mapped correctly to the new system, and unstructured notes often require manual review or transformation to preserve clinical meaning.

Example: A medication may appear as “Amoxicillin 500mg” in one system, while the start/stop date is recorded in free text elsewhere. Without careful review, the new system may interpret the medication as active indefinitely, creating a clinical risk.

2. Workflow Interdependencies

Clinics develop workflows that often rely on informal practices:

  • Nurses tracking immunizations in hidden fields
  • Front desk staff keeping notes outside the system to monitor authorizations
  • Billing teams running custom weekly exports

When these practices are embedded in daily operations, migrating without understanding them can break essential processes. An electronic health record migration is as much about workflows as it is about data, ignoring this leads to staff frustration and operational disruption.

3. Staff Adaptation and Change Management

Change is stressful. Staff accustomed to old habits may resist the new system, even if it is more efficient:

  • Fear of losing access to familiar information
  • Concern about learning new interfaces during busy clinic hours
  • Worry about potential errors affecting patient care

Effective migration must include training, continuous communication, and phased adoption strategies to manage resistance and build confidence.

4. Technical Integration and Compatibility

Legacy EHR systems often have customized fields, integrations, and third-party interfaces. When migrating to a new system:

  • Field definitions may differ
  • Report logic may not translate exactly
  • External integrations (labs, pharmacies, billing) may require reconfiguration

This makes EHR system migration a delicate technical endeavor requiring collaboration between IT staff, vendors, and clinical leadership.

EHR System Limitations

Understanding limitations of both legacy and new systems is critical to a successful migration. Recognizing what the systems can and cannot do informs planning, prioritization, and realistic expectations.

1. Legacy System Limitations

  • Hidden workarounds: Staff may rely on manual steps to compensate for system gaps
  • Inconsistent reporting: Quality metrics may not accurately reflect care delivered
  • Outdated interfaces: Incompatible with newer standards like HL7 or FHIR
  • Custom fields with ambiguous meaning: Often undocumented, leading to misinterpretation during migration

2. New EHR System Limitations

  • Strict field definitions: Some systems enforce standardized coding, limiting flexibility
  • Template differences: Custom templates may need recreation
  • Limited migration tools: Some systems only support bulk imports or have constraints on data types
  • Operational constraints: Some workflows from the legacy system may not transfer efficiently, requiring redesign

Connection to migration strategy: Limitations of both systems determine what can be directly transferred, what needs transformation, and what must be rebuilt manually. Planning around these limitations reduces errors and prevents staff frustration.

EHR Migration Risks

Even with careful planning, risks are inherent in any EHR migration. A clinic must identify, assess, and mitigate these risks to protect patient safety and operational continuity.

1. Data Integrity Risks

  • Missing records, incorrect lab results, incomplete medication histories
  • Duplicates or misaligned patient demographics
  • Misinterpretation of custom fields

Mitigation: Batch testing, automated and manual verification, clinician review of extracted records

2. Clinical Risks

  • Inaccurate data can lead to inappropriate clinical decisions
  • Missing stop/start dates for medications can cause adverse drug events
  • Unclear lab results without reference ranges can be misread

Mitigation: Maintain context during extraction, include unstructured notes when needed, verify with clinicians

3. Operational Risks

  • Billing errors, delayed claims, misrouted referrals
  • Lost productivity as staff adapt to new workflows
  • Confusion over temporary manual workarounds

Mitigation: Plan phased rollout if needed, train staff on real workflows, monitor parallel operations

4. Staff and Cultural Risks

  • Resistance to change
  • Increased stress and fatigue during transition
  • Reduced trust in the EHR if initial migration appears error-prone

Mitigation: Build a cross-functional transition team, provide continuous training, acknowledge staff stress, and integrate feedback loops

How Understanding Challenges Inform a Successful EHR Data Migration Strategy

After understanding the challenges, system limitations, and risks, it becomes clear that successful electronic health record migration requires deliberate planning and execution. Best practices serve as guiding principles to prevent errors, protect patient safety, and ensure staff confidence.

1. Begin with a Comprehensive Assessment

  • Inventory all data, workflows, templates, and manual workarounds
  • Engage all stakeholders: front desk, clinical staff, billing, and IT
  • Identify pain points and workflow dependencies that may not be obvious from the system alone

For example: A scheduler may track insurance authorizations in a spreadsheet because the old EHR cannot generate accurate alerts. Capturing this insight ensures the new EHR will accommodate or replace this workflow.

2. Classify Data Intentionally

Not all information needs the same treatment during healthcare data migration.

Data TypeRecommended ApproachExample
Active patient chartsStructured migrationRecent visits, medications, allergies
Historical recordsArchive as read-onlyOlder visit notes, closed episodes
Unstructured notesManual review or recreationFree-text clinical notes with important context
Problem lists / custom fieldsTransformation & cleanupDeduplicate, map codes, normalize statuses

For example: Classification determines the effort required and sets expectations for staff after go-live.

3. Test Early and Often

  • Perform small batch extractions to validate mapping and transformation rules
  • Include clinical staff in verification to ensure context is preserved
  • Adjust extraction or transformation processes before full-scale migration

For example: Test moving 50 patient records and check that:

  • Medications include stop/start reasons
  • Labs include reference ranges
  • Notes are complete and searchable

4. Build a Transition Team

A cross-functional transition team is essential:

  • Clinical representatives: Providers, nurses, care coordinators
  • Operational representatives: Front desk, billing, admin staff
  • Technical representatives: IT, vendor support

Responsibilities:

  • Make decisions on data classification and workflow redesign
  • Resolve conflicts between departments
  • Monitor progress and keep the project aligned with clinic priorities

Expert Advice/Best practice: Give team members protected time and decision-making authority to prevent migration from becoming “extra work.”

5. Train Staff Using Real Workflows

Training must reflect actual clinic operations, not just buttons and menus:

  • Check-in procedures, including late arrivals and insurance verification
  • Documentation for complex visits
  • Lab ordering and reconciliation
  • Medication refills with stop/start dates
  • Charge capture and claim submission

Post-go-live: Training continues through mentorship and ongoing support, not just a one-time session.

6. Communicate Clearly and Manage Stress

Migration introduces stress and fatigue:

  • Adjust schedules where possible
  • Reduce visit volume during critical migration phases
  • Provide clear escalation paths for problems
  • Offer safe spaces for staff feedback

Outcome: Staff feel heard, supported, and more willing to adopt the new system.

Step-by-Step EHR Migration Process

With best practices in place, the next step is the step-by-step, actionable process. Each stage connects naturally to the previous and next steps.

Step 1: Pre-Migration Planning

Objectives: Identify scope, resources, risks, and priorities

Actions:

  1. Inventory all structured and unstructured data
  2. Map workflows and manual workarounds
  3. Identify stakeholders for the transition team
  4. Decide goals for migration: patient safety, operational efficiency, compliance

Tips:

  • Document everything; assumptions lead to errors
  • Prioritize critical workflows that must work immediately after go-live

Step 2: Data Classification and Transformation

Objectives: Determine how each type of data will be migrated

Actions:

  1. Categorize data: direct transfer, transformation, archive, manual recreation
  2. Define transformation rules for medications, labs, problem lists
  3. Create mapping tables between old and new EHR fields

For example:

  • Lab codes converted to standardized LOINC codes
  • Duplicate allergies removed and mapped to correct patient

Step 3: Data Extraction

Objectives: Safely remove data from the legacy system without losing context

Actions:

  • Export in small batches first
  • Preserve clinical context (notes, start/stop dates, lab reference ranges)
  • Validate each batch with clinical staff

Expert Advice/Best practice: Keep logs of every extraction for auditing and troubleshooting

Step 4: Data Import and Verification

Objectives: Ensure data is accurate and usable in the new system

Actions:

  1. Import batches into the new EHR
  2. Perform three layers of verification:
    • Automated counts (patients, visits, medications, labs)
    • Spot checks for critical records
    • Clinical review to confirm charts tell the same story
  3. Adjust import rules and retest if discrepancies are found

Step 5: Implementation Rollout

Objective: Transition users to the new EHR without operational disruption

Options:

  • Full rollout: All staff start on the same day
  • Phased rollout: Gradual transition by department, provider, or workflow

Tips:

  • Align rollout strategy with staff capacity, patient volume, and risk tolerance
  • Plan for parallel operation if using phased rollout
  • Ensure IT and transition team are on standby for immediate support

Step 6: Staff Training and Adoption

Objective: Equip staff to work efficiently and confidently

Actions:

  1. Conduct scenario-based training reflecting actual clinic workflows
  2. Train staff on what to do when data is missing or unclear
  3. Provide ongoing mentorship post-go-live

For example: Train nurses on documenting complex visits where prior notes were previously free-text only

Step 7: Post-Go-Live Monitoring and Continuous Improvement

Objectives: Identify and resolve issues quickly, rebuild trust in the system

Actions:

  1. Monitor workflow bottlenecks and error rates
  2. Gather feedback from staff regularly
  3. Apply quick fixes for small issues and track larger issues for systematic resolution
  4. Adjust training and documentation as needed

Outcome: Over time, staff adopt the new EHR confidently, workflows are efficient, and data integrity is restored.

Step 8: Reconnect the EHR to Clinic Purpose

Migration is not complete until the EHR supports care instead of dictating it:

  • Ensure workflows reflect how care is actually delivered
  • Reduce unnecessary steps and manual workarounds
  • Reinforce staff confidence in the system

Enable growth, telehealth, RPM, and future enhancements
