Rocket Software Mainframe Cost Optimization.

Rocket Software assembled its portfolio through acquisition: the ASG estate in 2021, then OpenText's Application Modernization and Connectivity business, the Micro Focus heritage products, in a $2.275 billion deal closed in 2024. The result for buyers is a vendor whose contracts, metrics, and product overlaps came from three different companies. That history is where the savings live.

Three heritage stacks, one invoice.

A typical Rocket estate now mixes native Rocket products (BlueZone terminal emulation, Mainstar, iCluster, the MultiValue databases), ASG heritage tooling, and Micro Focus heritage products such as Rocket Host Access (formerly Micro Focus RUMBA), Reflection, Extra!, Verastream, and the Enterprise Suite COBOL toolchain. Each heritage stack arrived with its own metrics, its own support terms, and its own audit clauses, and the patterns we commonly see after this kind of consolidation are predictable: overlapping products licensed in parallel for the same users, support renewing on software deployed nowhere, and pricing structures nobody has rebased since the paper changed hands.

Post acquisition vendors typically standardize pricing upward over time and consolidate customers onto new agreements. That migration moment is leverage, in both directions. Handled passively, it is where uplifts land. Handled deliberately, it is where a decade of accumulated overlap gets cashed out. The difference is preparation, and it is the core of our cost optimization practice.

Our approach · five steps

1 Step 01

Baseline the inherited estate

Every Rocket, ASG heritage, and Micro Focus heritage entitlement, the contract each one lives on, the metric it is priced on, and its renewal date. Estates assembled by acquisition rarely have this in one place, on either side of the table.

2 Step 02

Measure real usage

Deployed seats, concurrent peaks, and actual product usage against what each contract charges for. Terminal emulation is the usual headline: named user counts commonly exceed measured concurrent usage by a wide margin.

3 Step 03

Find the overlap

Duplicate function across heritage stacks: multiple emulators serving one user base, two products doing one job, support streams on shelfware. Each finding is quantified in dollars and staged by ease of capture.

4 Step 04

Design the target position

The consolidated agreement you should hold: which products stay, which retire, which metric each is priced on, and what the credible alternative is for every line that remains. Designed before Rocket proposes its own version.

5 Step 05

Capture it in the contract

The savings case carried into the renewal: retirements credited, metrics rebased on measured usage, uplift caps and true down rights locked in. Optimization that never reaches the paper typically leaks back within two cycles.

What changes with us on the case.

Rocket's account team knows what the combined portfolio should yield from your account. With us engaged, you know what it should cost instead. Every overlap is documented before the renewal conversation starts, every metric proposal arrives with your measured numbers attached, and every uplift claim meets a prepared alternative. Across 500+ engagements and $180M+ of negotiated mainframe spend, prepared buyers typically close 20 to 35% below the vendor's opening renewal position.

What you get

  • A complete entitlement and deployment map across all three heritage stacks
  • A quantified overlap and shelfware register, ranked by savings and ease of capture
  • A target agreement design with measured usage behind every metric
  • Renewal execution that converts the findings into contracted savings

Frequently asked

Q1

Why do Rocket estates carry so much overlap?

Acquisitions. The ASG portfolio arrived in 2021 and the Micro Focus heritage AMC business in 2024. Many enterprises now hold emulation, modernization, and management tooling from two or three heritage stacks under one vendor, often with duplicate function and separate support streams.

Q2

Where does the money typically hide?

Overlapping terminal emulation licensed per seat for the same users, support renewing on undeployed products, and inherited contract language priced on metrics that no longer match usage. Each is recoverable with documentation and timing.

Q3

Can we consolidate emulation onto one agreement?

Typically yes, and it is one of the strongest levers. A consolidation negotiated on a measured concurrent user count commonly costs less than the sum of the legacy renewals. The leverage exists before you sign the consolidated agreement, not after.

Q4

Does Rocket audit its customers?

Compliance reviews are commonly observed, particularly around seat counts on emulation products and entity coverage after M&A. Acquired paper often carries audit clauses written by the original vendor; knowing which clause set governs your products is part of the baseline work.

Q5

What does an engagement look like?

Baseline the entitlements, measure usage, quantify the overlap, design the target agreement, then carry it into the renewal. Across 500+ engagements, prepared buyers typically close 20 to 35% below the vendor's opening position.
