Query Wizard
Build Data Migration Tests
Without Writing SQL
Quickly create source-to-target comparisons. Check migrated tables, columns, and row counts to uncover differences before cutover.
Make Data Validation Part of Your Migration
Moving to the cloud, replacing a legacy database, or upgrading your platform?
Missing records, truncated text, and values placed in the wrong columns can carry migration problems into your reports and business applications.
QuerySurge’s Query Wizard helps your team quickly create comparisons for data that should move unchanged.
Its guided interface enables you to build tests without writing SQL, while helping experienced users reduce repetitive query development.
Three Ways to Validate Your Migrated Data
Table-Level Comparison |
Column-Level Comparison |
Row-Count Comparison |
|---|---|---|
| Compare the complete source and target tables to determine which data should move unchanged. | Validate selected fields, including unchanged columns in tables that also contain transformed data. | Identify differences in record totals. Add table or column comparisons to verify data values. |
Faster Test Creation. Repeatable Validation.
- Connect visually:
Link corresponding tables and columns through drag and drop. - Focus your testing:
Filter column comparisons by date, migration batch, or other criteria. - Reuse your tests:
Repeat validation across trial loads, migration waves, and fixes.
For transformed data, extend the generated SQL or explore QuerySurge AI to easily create tests.
