What really slows down IBM Z modernization?

It’s not the application code.

In this episode of Skyward Data, Dusty Froyum (Co-Founder, VirtualZ) and Marc Sokol (Executive Chairman, former SVP at CA Technologies) break down what’s actually happening inside enterprise VSAM → PostgreSQL migrations — and why data execution is often the hardest part to get right.

They walk through real-world results, including:

But the conversation goes beyond performance.

You’ll hear how modernization efforts often start as “simple migrations” — only to become complex when data dependencies, stale datasets, and heavy ETL or CDC architectures enter the picture.

Marc shares firsthand experience from decades in the mainframe world, including why so many migration programs slow down at the data layer — and what changes when execution becomes predictable.

Dusty outlines how a no-code, direct-access approach can simplify architecture, reduce operational complexity, and help teams meet tight migration windows without over-engineering the solution.
