UniBasic to Java Migration, Automated. Leave UniData Behind Without Rewriting a Line by Hand.
UniData license fees keep climbing. UniBasic talent keeps retiring. Our automated UniBasic migration platform converts your entire UniData estate, including UniBasic programs, dictionaries, and phantom jobs, to maintainable Java and SQL, with 95%+ of code converted automatically and every program validated for functional equivalence.
Your Legacy Stack Is a Growing Liability
Enterprises running UniData and UniBasic applications face a squeeze from every direction, and standing still is the most expensive option of all.
Rising License Fees
A single vendor controls the platform and the pricing. Every renewal cycle, the cost of standing still goes up, with no added business value in return.
Vanishing Talent
The engineers who know UniBasic and MultiValue databases are retiring. Every departure takes irreplaceable institutional knowledge with it.
Vendor Lock-In
A proprietary MultiValue database isolates your data from modern analytics, integrations, cloud platforms, and the entire SQL ecosystem.
Manual Rewrite Is Impossible
With millions of lines of code, rewriting program by program takes years, costs a fortune, and almost always fails. You need automation.
Automated UniBasic to Java Conversion, Proven at Enterprise Scale
Our conversion platform parses your entire UniData estate, not just the UniBasic code, and generates modern, readable Java with a relational SQL schema. Not a black-box emulation, but a real system your team can own and evolve.
95%+ Automated UniBasic Conversion
Our tools translate UniBasic programs and subroutines into structured, readable Java automatically. Only edge cases need expert attention.
MultiValue → Relational SQL
UniData hashed files, dictionaries, and multivalued fields become a normalized relational schema on the SQL database of your choice: PostgreSQL, Oracle, SQL Server, and more.
Functional Equivalence Testing
Every converted program is validated with side-by-side output comparison against the legacy system. Same inputs, same outputs. Proven, not promised.
Maintainable, Not Emulated
You get Java source with a modern build, deployable on-premise or in the cloud. Phantom jobs become scheduled Java services, so the whole estate moves, not just the code.
A Proven Five-Step UniBasic Migration Process
De-risked, repeatable, and transparent: you see progress at every stage, and your business keeps running throughout.
Assess
We inventory your full UniData estate with automated tools: programs, dictionaries, phantom jobs, dependencies, dead code, and complexity hotspots.
Pilot
We convert a representative slice of your application and demonstrate functional equivalence before you commit to the full migration.
Convert
Our platform migrates the full codebase to Java and your MultiValue data to a relational SQL schema, at a pace manual rewrites can't touch.
Validate
Automated side-by-side testing compares legacy and converted systems across your real workloads until outputs match, every time.
Cut Over
Phased go-live with parallel running, rollback safety, knowledge transfer, and post-migration support for your team.
Automated UniBasic Migration vs. the Alternatives
Three paths forward. Only one eliminates license costs, preserves your business logic, and lands you on a mainstream stack in months.
| Stay on UniData | Manual Rewrite | Our Automated Migration | |
|---|---|---|---|
| License costs | Rising every renewal | Paid throughout multi-year rewrite | Eliminated at cutover |
| Timeline | Risk grows indefinitely | 3 to 7+ years, often abandoned | Months, not years |
| Business logic | Preserved but frozen | High risk of loss and regressions | Preserved and verified 1:1 |
| Talent pool | Shrinking MultiValue specialists | Mainstream Java | Mainstream Java & SQL |
| Risk | Compounds every year | Very high failure rate | De-risked via pilot & equivalence testing |
Proven Tools. Proven Process. Proven Results.
This isn't theory. Our platform and methodology have carried enterprise MultiValue systems into the Java world, successfully and verifiably.
Of UniBasic code converted automatically by our platform, dramatically reducing cost, timeline, and human error.
Millions of lines of legacy code successfully migrated across completed enterprise projects.
Of converted programs validated through side-by-side functional equivalence testing before go-live.
Black boxes. You receive readable Java source code and a documented SQL schema. Full ownership, no new lock-in.
UniBasic Migration Questions Enterprises Ask Us
What is UniBasic, and why migrate it to Java?
UniBasic is the BASIC-derived programming language used in Rocket UniData and UniVerse MultiValue systems. Most UniBasic applications were written in the 1980s and 1990s and still run core business processes. Migrating UniBasic to Java removes dependence on a shrinking pool of MultiValue developers, eliminates UniData license fees, and moves your application onto a platform with a large, current talent market and modern tooling.
How does automated UniBasic to Java migration work?
Our platform parses every UniBasic program, subroutine, and dictionary in your UniData estate and generates equivalent Java, while MultiValue files are mapped to a normalized SQL schema. Each converted program is then run against recorded production inputs to prove functional equivalence with the original UniBasic. The result is a UniBasic migration that is fast, repeatable, and verified rather than hand-rewritten.
Will the converted Java code actually be maintainable?
Yes. To be transparent: transpiled code is not fully idiomatic Java, since it retains some structure from the original UniBasic. But it is well-organized, readable, and thoroughly manageable, not machine-generated spaghetti or a runtime emulator. Any Java developer can read, test, and extend it, and it can be refactored incrementally over time. We include documentation and knowledge transfer so your team is productive immediately.
How do you handle the MultiValue database?
UniData files, dictionaries, and multivalued fields are mapped to a normalized relational schema. Data is migrated with automated validation, and you choose the target SQL database: PostgreSQL, Oracle, SQL Server, or another engine that fits your standards.
What about the 5% that isn't converted automatically?
Complex or ambiguous constructs are flagged by the platform and handled by our migration engineers. Every manually-touched program goes through the same functional equivalence testing as automated conversions.
What about phantom (batch) jobs?
They're part of the migration, not an afterthought. Phantom processes become scheduled Java services, and the assessment phase inventories them along with the rest of your estate so nothing is missed.
How long does a migration take?
It depends on codebase size and complexity, but automation compresses timelines from years to months. The assessment phase gives you a concrete, evidence-based estimate before you commit.
Can we keep operating during the migration?
Yes. Your production system runs untouched while we convert and validate. Cutover is phased, with parallel running and rollback options, so business continuity is protected throughout.
