Performance & legacy modernization

Axio Intelligence makes slow or aging systems fast and maintainable again — profiling and fixing performance bottlenecks, tuning databases and APIs, migrating platforms, and rewriting legacy components incrementally behind stable interfaces so the business never has to stop shipping.

When teams call us

You probably need this if…

  • 01

    Pages, APIs or reports got slow as data grew, and nobody owns performance.

  • 02

    A legacy system blocks new features and only one person understands it.

  • 03

    You need to migrate clouds or off a platform without a customer-facing outage.

Deliverables

What you get

01

Performance profiling

Measure first: tracing, query analysis and load tests against realistic data.

02

Targeted fixes

Indexing, caching, query rewrites, async processing and right-sized infrastructure.

03

Incremental rewrites

Strangler-pattern replacement, one bounded component at a time, with parity tests.

04

Migrations

Cloud-to-cloud and platform exits run as small, reversible steps.

Named platforms and standards describe what we build with and build to; they don’t imply a formal partnership or certification with the vendor.

Questions

Performance & legacy modernization: common questions

Do we have to freeze features during a rewrite?

No. We replace components incrementally behind stable interfaces, with parity tests, so product work continues while the old system is retired piece by piece.

Do you modernize COBOL or RPG on IBM mainframes and IBM i?

Yes, one job at a time. We move COBOL and RPG workloads off z/OS and IBM i to AWS, Azure or Google Cloud in a modern language, starting with the batch and extract jobs that cost the most, and dual-run them until the outputs match. See mainframe & IBM i migration.

Do you migrate Oracle or SQL Server to PostgreSQL?

Yes. We convert schemas and stored procedures, keep data in sync with change data capture, and cut over with a rollback path. See database migration.
