Mainframe Modernization Services
We move mainframe workloads in planned waves, with each wave proven in a parallel run before cutover.
Mainframe modernization services are the assessment, planning, and engineering work that moves COBOL, PL/I, and assembler workloads off IBM z/OS, or opens them to newer systems where they stay. We choose a path for each workload: retain it and integrate through APIs, rehost it on a mainframe-compatible runtime, refactor the code to Java, rewrite the domain, or replace it with a package. Each move group carries its data, batch jobs, and interfaces, and it cuts over only after a parallel run shows the new system produces the same results as the old one.
Programs usually start from a date: a hardware lease or IBM contract renewal, an outsourcing agreement that expires, the retirement of the people who know the batch schedule, or a product the business cannot launch on the current code. The planning question is which workloads move first. Under IBM's traditional sub-capacity pricing, the software bill follows the peak four-hour rolling average of processor use, so savings arrive when the workloads that create the peak leave.
Mainframe programs run with our Andersen Consulting colleagues, including SPR's custom software and cloud modernization teams, under one plan and one accountable lead. BD Emerson's security and compliance practitioners sit on the same team, so access controls, audit trails, and the evidence examiners ask for move with each workload.
We inventory the code and data, attribute processor use to workloads, and map every contract renewal and notice period. BD Emerson's planning range for a large estate is 8 to 12 weeks.
We carry one domain of moderate complexity through conversion, parallel run, and the shutdown of the mainframe code it replaced, which calibrates the estimate for every later wave.
Waves follow data dependencies and economics. Peak-driving workloads and whole logical partitions leave early, so the bill falls in steps the business case can count.
A wave counts as finished only when the old code is switched off. The final exit lands on a hardware or contract date, and your team owns the code, the runbooks, and the tests.

We model the bill from your contract and your usage data before anyone picks a tool, so the wave plan follows the workloads that drive cost and the dates that end contracts.
BD Emerson's security and compliance practitioners join the program, so access controls, audit trails, and the evidence auditors and examiners ask for are designed into each target environment.

We had a hard time finding the right company to partner with in support of our compliance journey. Some vendors sell the idea that they do the work, but then you end up doing everything. The ambiguity is what killed our last project. BD Emerson’s team has such great technical knowledge and understands the standard so well that they made us comfortable with moving fast. This has led to us closing major enterprise customers that were previously out of reach because of security and compliance.
Lead an enterprise initiative to overhaul the organization's technology stack from ecommerce, corporate tech, and corporate security.
Supported ISO 42001 exercise and served as internal auditor.
Rubrik's privacy and compliance team began with the backbone of BD Emerson. BD Emerson supported building out the privacy program, GRC (ISO 27001, SOC 2, CMMC, FedRAMP), and the appsec function.
We needed a partner who could move quickly, without sacrificing precision. BD Emerson brought the expertise, structure, and speed we were looking for. Their team became an extension of ours, embedding themselves across the organization, guiding us step by step, and giving us confidence in areas we hadn’t tackled before. The internal audit they conducted was so detailed that even the external auditors called it out. Achieving ISO 27001 with zero nonconformities says everything you need to know about the quality of the partnership.
