Modernise

Move your Transact estate forward without carrying every legacy decision with it.

SEMTEXX helps teams plan and deliver Transact modernisation across versions, runtimes, local development, data and delivery practices.

Why it matters

An upgrade is rarely just a technical installation. Existing product behaviour, local code, interfaces, data quality, operational procedures and release practices all shape the risk. Treating them separately creates late surprises.

We connect the functional and technical views early so that the modernisation path is grounded in how the bank actually works.

What we help with

• Transact version upgrade assessment and planning
• TAFC-to-TAFJ transition
• InfoBasic and legacy local-development review
• Java API adoption and local code conversion
• customisation rationalisation and replacement with standard capabilities
• data analysis, mapping, migration and reconciliation
• interface impact analysis
• upgrade testing and defect resolution
• deployment, DevOps and release-process improvement
• go-live readiness and stabilisation

How we work?

Understand the estate

Map the business-critical behaviour, local changes, interfaces, data dependencies and operational constraints.

Choose the modernisation path

Separate what must be preserved, changed, retired or redesigned. Make dependencies and trade-offs explicit.

Engineer and validate

Implement targeted changes and test functional behaviour, technical compatibility and operational readiness together.

Stabilise the outcome

Support the transition, resolve emerging issues and leave the team with clearer control of the new estate.
