Case Study: Practice Migrate

How CapMinds Helped a Leading Texas Practice
Migrate 500K Patient Records in 12 Days

Client Overview

The client is a multi-specialty healthcare practice in Texas serving patients across three counties with a focus on coordinated, value-based care. The network operates seven outpatient facilities, supported by 120+ physicians, 40 nurse practitioners, and 300+ staff. Offering services in family medicine, pediatrics, internal medicine, behavioral health, and women’s health, the practice manages over 1,200 daily encounters, including telehealth visits.

The organization operates with an in-house lab and imaging services and maintains a strong commitment to CMS and HIPAA compliance. In 2024, they partnered with CapMinds to execute a large-scale health data migration, modernizing its EHR infrastructure for secure, real-time, and scalable data management across all locations.

Challenges Faced Before Migration

Before partnering with CapMinds, the Texas-based healthcare practice faced several operational and data challenges that hindered performance and compliance:

  • Fragmented patient data across multiple sites, causing duplicates and inconsistencies
  • Frequent downtime and slow performance during peak hours disrupt care delivery
  • Lack of interoperability with new systems like HIEs, labs, and telehealth platforms.
  • Manual data backups and limited security controls pose HIPAA compliance risks
  • Scalability issues arose as patient volume and provider count rapidly increased

These challenges created workflow bottlenecks, reporting delays, and growing data integrity risks, prompting the need for a secure, high-speed EHR migration led by CapMinds.

CapMinds’ Proven 4-Phase Data Migration Approach

CapMinds implemented a secure, structured, and automation-driven data migration framework designed to ensure accuracy, compliance, and minimal operational disruption.

Our approach combined technical precision with healthcare workflow understanding, enabling the Texas-based practice to move 500K patient records seamlessly within 12 days.

Highlights:

Pre-Migration Assessment & Data Mapping:CapMinds initiated a full EHR infrastructure audit to identify source databases (MySQL and MSSQL instances), schema variations, and critical dependencies.

  • Built a data-mapping matrix aligning 250+ data fields (demographics, encounters, CPT, ICD-10, lab orders, documents) between legacy and target EHRs.
  • Created custom mapping scripts in Python for structured JSON extraction and field normalization
  • Conducted mock migrations using anonymized datasets to validate schema compatibility and timestamp synchronization.

Data Cleansing & Validation:Before migration, CapMinds implemented a two-layer validation process combining automation and manual QA.

  • Used deduplication algorithms to eliminate 12K duplicate MRNs and inactive accounts
  • Applied FHIR and HL7-V2 validation tools to check data format integrity before transformation
  • Partnered with the client’s clinical data team to verify 50 random patient charts per department for accuracy and completeness.

Secure Extraction, Transformation & Transfer: All data transfer activities adhered to HIPAA, SOC-2, and NIST 800-53 standards.

  • Encrypted pipelines (AES-256 + TLS 1.3) were used for secure point-to-point transmission
  • Data was transformed into FHIR-R4 compatible JSON bundles, enabling smoother integration with HIE and third-party applications
  • Real-time checksum validation was implemented to detect any record mismatches mid-transfer
  • Leveraged AWS EKS auto-scaling for compute bursts, cutting total transformation time by 38% compared to the baseline test.

Migration Execution & Post-Go-Live Support CapMinds executed the final migration over a 72-hour controlled cutover during a weekend window.

  • Incremental loads were synchronized every 6 hours, ensuring no data freeze or downtime
  • Post-migration, a comprehensive audit trail verified all 500K records with a 99.98% validation pass rate
  • Provided 24/7 post-go-live monitoring, issue triage, and query performance tuning
  • Delivered custom training sessions for admin and billing teams to ensure smooth adoption of the new system.
