Database Migrations
Moving databases is high-stakes work. A botched migration means lost records, broken applications, and angry users. We plan every migration down to the row, run parallel validation, and execute cutover with rollback plans in place so your data arrives intact.
How We Work
Source Audit & Assessment
We inventory every table, view, stored procedure, trigger, and scheduled job in your current database. You get a complete map of what exists, what is actively used, and what can be archived.
Schema Design & Mapping
We design the target schema, accounting for data type differences, encoding issues, and normalization improvements. A field-by-field mapping document ensures nothing is missed.
Migration Scripting & Dry Runs
Automated migration scripts are built and tested against a copy of your production data. We run multiple dry runs, comparing row counts and checksums until the output matches expectations exactly.
Cutover & Validation
The live migration executes during a planned maintenance window. Automated validation compares source and target databases row by row. Applications are switched over only after validation passes.
