Our migration approach offers our customers a way forward plan to seamlessly update and modernize their technology with our proven 3-step process.

Step 1

Scope, Architecture Design, and Planning

  • Define the governing factors for the migration:
  • Capacity - Determine the data that needs to be migrated along with data reliance, freshness, and encryption requirements
  • Currency - Factor in # of Users
  • Consumption - Define the application interoperability and data usage requirements
  • Compute - Scope I/O requirements

Step 2

Migration Implementation - Parallel Strategy

  • Database Build and Migration:  Source > Stage > Production
  • Redirect ETL Jobs Source > Stage > Production
  • Rebuild BI Analytic Access Layer
  • Redefine Users and Access Rights
  • Testing and Final Q/A
  • Complete Cutover

Step 3


Once the migration is complete, it is essential to ensure that it is optimized, secure, and accessible.  In addition, monitor the implementation for real-time changes to infrastructure and workloads.
