AIX → Linux Migration Regression Utility

An Ab Initio regression utility comparing AIX and Linux graph outputs and table loads, behind a zero-data-loss migration.

data lost in the migration
0

Context

Large-scale data quality and EVM projects were moving from AIX to Linux.

Problem

The migration needed evidence that every graph produced identical outputs and table loads on the new platform.

My role

I built the regression utility.

Approach & architecture

  • Compared AIX and Linux graph outputs and table loads.
  • Produced detailed Excel migration reports.

Results

  • Migration completed with zero data loss.

Tech stack

  • Ab Initio
  • Data Quality
  • AIX
  • Linux

What I'd do next

  • Generalise the comparison into a reusable platform-migration test harness.
