How Z Asset Optimizer Transforms License Cost Visibility Before You Modernize
Are You Paying for Mainframe Software Nobody Uses?
The Uncomfortable Truth About Mainframe Software Estates
What if 30% of your mainframe software is unused — but still costing you money every single month?
This isn’t a hypothetical. It’s the reality in many enterprises running z/OS® environments today. Over decades of operation, mainframe estates accumulate hundreds of software products — installed for a project, a team, or a requirement that no longer exists. But the licenses? They keep renewing. The MSU consumption? It keeps ticking.
When organizations begin their mainframe modernization journey, they often discover that their migration scope is bloated with software that hasn’t been touched in years. Obsolete versions. Unused libraries. Products with zero active users. All of it inflating cost estimates, distorting timelines, and adding risk to an already complex transformation.
The solution starts with visibility.
What Is Z Asset Optimizer — and Why Does It Matter?
Z Asset Optimizer runs natively on z/Architecture® mainframes under the z/OS® operating system — meaning it works inside your environment, not outside it. No agents to deploy on distributed systems. No guesswork from external scanners.
Its purpose is precise and powerful:
Discovery & Identification It catalogues every software product installed on your z/OS platform — giving you a complete, accurate picture of what exists in your environment, not just what you think exists.
Usage Monitoring & Trend Analysis It tracks actual software usage over time — identifying which products are actively used, which are declining, and which have gone completely dormant. Usage trends across libraries give you the full picture.
MSU Capacity Reporting It reports the MSU (Million Service Units) capacity consumed per system for each product — giving your team the hard data needed for licensing conversations with vendors and accurate cost modelling.
Obsolete Version Identification It flags outdated versions of software still in active or passive use — so you know exactly what needs to be retired, upgraded, or excluded from migration scope.
The Four Business Outcomes That Matter
- Cut Licensing Costs With ConfidenceWhen you know precisely which software is unused, you can have an evidence-based conversation with your vendors. Renewals that previously went unquestioned can now be challenged, renegotiated, or cancelled entirely.
- Right-Size Your Migration ScopeOne of the biggest cost drivers in mainframe modernization is scope creep — carrying everything forward without questioning whether it needs to go. Z Asset Optimizer ensures you migrate only active, relevant assets. Dead weight stays behind.
- Build Accurate Migration EstimatesTimelines built on inflated asset lists are timelines that will slip. When your scope is clean — validated by actual usage data — your estimates become defensible, your planning becomes reliable, and your stakeholder confidence goes up.
- Retire Obsolete Software ProactivelyObsolete versions are a security risk, a compliance risk, and a support cost. Identifying and retiring them before modernization — not during — removes a significant source of downstream risk.

Our Mainframe Asset Assessment leverages Z Asset Optimizer to deliver:
- A complete software inventory of your z/OS environment
- Usage analysis mapped to actual business activity
- License cost impact reporting with savings opportunity identification
- A prioritized list of assets recommended for migration, retirement, or consolidation
The output is a clear, data-driven foundation for your modernization roadmap — one that your finance, operations, and architecture teams can align on.
Before You Modernize, Know What You Own
Mainframe modernization is a significant investment. Organizations that begin with asset clarity consistently achieve better outcomes — lower costs, tighter timelines, and fewer surprises mid-migration.
