Use Cases

One platform, many paths. All of them yours.

Every transformation path runs on the same engine. Start with the one that solves your most pressing problem — the others stay open.

The issue
Mainframe costs and risk keep climbing — but a rewrite is the one thing you can't afford.
The SHIFT approach
Scan the workload and fix the scope
Compile the original code natively for Linux and cloud
Cut over incrementally — integrity preserved
Off the mainframe fast, with data and source integrity preserved.
Mainframe
costly, rigid
SHIFT
compiles natively
Linux / Cloud
fast, low risk
The issue
Decades of accumulated code — nobody knows what's still alive.
The SHIFT approach
Run legacy and modern languages in one environment
Dead code surfaces naturally as you work
Refactor non-disruptively, at your pace
A cleaner estate, refactored without a single outage.
Legacy code
COBOL, PL/I
SHIFT
one environment
Clean estate
dead code gone
The issue
Your target architecture is blocked because legacy data can't be touched.
The SHIFT approach
Modern code reaches legacy datastores directly
Design and validate the new architecture in parallel
Switch when proven — not before
A validated architecture, zero disruption along the way.
Modern code
Java, Python, Go
SHIFT
direct access
Legacy datastores
untouched
The issue
Some parts genuinely deserve a rebuild — but nowhere near all of them.
The SHIFT approach
The SDK opens legacy and modern datastores to every language
Rebuild the value-adding parts with true backward compatibility
Everything else keeps running as-is
Reimagined where it pays off; untouched where it doesn't.
Your estate
legacy + modern
SHIFT
backward compatible
Rebuilt
only what adds value
The issue
Auditors and regulators want decades of records — in their original form.
The SHIFT approach
Move data and code to an open platform with full integrity
Original-form retention with a complete audit trail
Modern reporting, KYC, and regulatory access with minimal effort
Compliance-grade retention, reachable by modern tools.
Original records
decades, as-is
SHIFT
full integrity
Open platform
reporting · KYC
The issue
One vendor controls your runtime, your pricing, and your roadmap.
The SHIFT approach
The same code and data run interchangeably on mainframe and Linux
Choose active-active, active-passive, or dual-stack
Negotiate from strength — or leave
Lock-in broken, compatibility intact.
One codebase
unchanged
SHIFT
same code & data
Two stacks
mainframe + Linux
The issue
Test environments on the mainframe are expensive and scarce.
The SHIFT approach
Spin up identical, compatible environments off the mainframe
Test with full confidence against production behavior
Pay a fraction of mainframe test/dev cost
Full testing confidence at a fraction of the cost.
Production
on mainframe
SHIFT
identical environment
Test env
fraction of the cost
