EHR data migration is one of the most critical (and risky) projects a healthcare organization can undertake. Patient histories, clinical documentation, scheduling data, billing information, and compliance records must transfer accurately and securely from one system to another. Any gaps can disrupt care, interrupt workflows, or create long-term data integrity issues.
Whether your organization is moving to a modern EHR for interoperability, scaling operations, or replacing legacy technology, having a structured plan is essential. This guide walks through a comprehensive checklist for each stage of the migration process: pre-migration planning, execution, and post-migration validation.
Successful EHR data migrations are built on thorough preparation. This phase ensures that the data you move is accurate, complete, and formatted correctly for the receiving system.
Before any data moves, review the existing system to understand:
• Data quality issues
• Duplicate or inactive patient records
• Missing or outdated demographic fields
• Inconsistent formats across providers or departments
This audit determines the scope of the migration and highlights areas requiring cleanup.
Clear goals guide the strategy. Examples include:
• Improved clinical documentation accuracy
• Better reporting and analytics
• Enhanced interoperability with labs or partners
• Reduced manual data entry and administrative time
Knowing your goals ensures the new EHR supports future workflows.
Include representatives from:
• IT
• Clinical leadership
• Billing
• Scheduling
• Compliance
• Vendor migration specialists
Each group provides vital input on workflows and data dependencies.
Data mapping defines how each field in your current EHR transfers into the new system. This includes:
• Demographics
• Clinical notes
• Medication lists
• Allergies
• Diagnoses and codes
• Orders
• Document attachments
Accurate mapping prevents data from landing in the wrong fields or being excluded entirely.
Data cleanup is one of the most important steps:
• Remove duplicates
• Standardize date formats
• Correct inconsistent abbreviations
• Ensure mandatory fields are populated
• Verify insurance and payer details
Clean data reduces errors during migration and improves downstream reporting.
Before importing data into the new EHR:
• Create secure, redundant backups
• Use multiple export formats if possible (CSV, XML, HL7 extracts)
• Document versions
• Ensure rollback capabilities
If anything goes wrong, you need the ability to restore original data.
Once the planning is complete, the migration process begins. This stage requires close monitoring and timely communication.
Run a migration using a sample dataset:
• 10–20 patient records
• Medication lists
• Clinical notes
• Billing history
• Scheduling data
Validate that everything lands correctly in the new EHR before moving the full dataset.
Your team should track:
• Import progress
• Data discrepancies
• Error logs
• Time estimates
• Fields that did not map as expected
Immediate visibility reduces the risk of undetected issues.
Daily or twice-daily updates keep everyone aligned. Your clinical and billing teams need to know:
• What data is currently migrating
• Whether downtime will occur
• What workflows may be temporarily affected
Common migration issues include:
• Missing mandatory fields
• Incorrect data types
• Mismatched date formats
• Character limit overflows
• Custom field compatibility problems
Resolving errors during migration reduces rework and delays.
Once the data lands in the new EHR, the real work begins. Validation ensures the accuracy and completeness of migrated records.
Review:
• Demographic accuracy
• Medication lists
• Problem lists and diagnoses
• Progress notes
• Allergies
Spot-check large batches of records to ensure consistency.
Test whether staff can complete key tasks:
• Document visits
• Enter vitals
• Order labs
• Route messages
• Access care plans
An EHR migration is not complete until clinical workflows function reliably.
Confirm accuracy across:
• Charge capture
• Coding
• Claims submission
• Clearinghouse connections
• Remittance posting
Billing disruptions are among the most costly migration failures.
A structured training plan helps reduce resistance and errors:
• Role-based training sessions
• On-demand training materials
• Go-live coaching
• Helpdesk escalation paths
For the first month:
• Hold weekly feedback sessions
• Track error patterns
• Identify workflow slowdowns
• Prioritize enhancement requests
This ensures continuous improvement after go-live.
Even well-planned migrations encounter challenges. Avoid these frequent errors:
• Migrating unclean or incomplete data
• Skipping validation steps
• Not performing a pilot migration
• Underestimating workflow disruption
• Lack of clinician involvement
• Overlooking payer and billing configurations
Proactive planning minimizes these risks.
EHR data migration doesn’t have to be disruptive. With a structured checklist, careful planning, and thorough validation, healthcare organizations can transition smoothly and improve clinical and operational performance in the process.
