Whether you are migrating from legacy systems to a new system, from one vendor’s software to another’s, or from on-premises to the cloud, Data Migration has become one of the most challenging initiatives for IT managers. Although these projects yield high business benefits, they tend to involve a high level of risk due to the volume and criticality of the data.

  • Data Migration: Scary Metrics

    • the average cost for a Data Migration = $875,000
    • 34% of migrations have missing or lost data
    • 38% have some form of data corruption
    • 64% of migration projects have unexpected outage/downtime
    • typical cost of downtime:
    • $6.5 million/hour - Brokerage industry
    • $2.8 million/hour - Energy Industry
    • 72% of organizations deferred because data migration is too risky
  • Data Migration: Key Risks

    • Unexpected downtime
    • Budget overruns
    • Customer or Brand Impact
    • Data corruption
    • Application performance issues
    • Data loss

    To reduce risk and ensure that the data has been migrated and transformed, you need to implement a thorough validation and testing strategy. QuerySurge helps you test your data quickly and easily.

Automating the Migration Testing Process: a 2-step process

Step #1: The Wizards — Fast & Easy. No Coding Needed.

In 2015 QuerySurge introduced our Query Wizards into the product. The Query Wizards help the team validate data with no coding required. They speed up the validation process dramatically and simplify the workload. The Wizards are useful for:

  • Quickly verifying table-to-table compares, validating hundreds of tables in minutes
  • Confirming that all rows have come over without issue and verifying row counts
  • Performing any necessary column-to-column compares
  • Verifying data types and data thresholds

Step #2: Testing the Transformations (ETL)

For data with transformations, you can create QueryPairs in our Design Library — one aimed at the existing system and one at the new system. You can run queries either immediately or at a particular date & time. Or they can be automatically triggered by an event, such as after your ETL or build process completes. This DevOps task is performed through the QuerySurge API. And reports can be automatically emailed to your team.

Supported Data Technologies

QuerySurge supports data warehouses, Hadoop lakes, NoSQL data stores, traditional databases, flat files, XML, web services, JSON, and many other data stores as either sources or targets.
