Real T24 knowledge. No waffle.
Practical articles and resources for T24 developers, support analysts, and consultants — built around the questions that come up in production, not the ones in the manual.
Who it is for
T24 developers
Articles that explain why things work the way they do, not just how. Faster debugging, fewer escalations, less time spent reinventing the same fix.
Support analysts
Patterns for diagnosing COB failures, interface issues, and production incidents before they escalate. Written by someone who has been on the call.
Migration teams
TAFC to TAFJ guidance built around real migration blind spots — not vendor documentation. What to test, what breaks, and what nobody tells you.
T24 consultants
Sharper interview answers, clearer positioning, and practical knowledge that makes you sound like you have been doing this longer than you have.
New joiners
A learning path that builds mental models before commands. Get useful in months instead of feeling lost for a year.
T24 fundamentals
At some point someone corrected you for saying T24 instead of Temenos Transact. Here is the full story — what changed, what did not, and what the architectural direction actually means.
AA and COB
A back-dated change triggers a full recalculation of the arrangement's history. This is reverse-replay — the most common source of AA production incidents and one of the least understood.
T24 fundamentals
OFS is how the outside world talks to T24. Once you understand the message structure, most integration problems become diagnosable in under a minute.
Why this exists
Official documentation covers the features. T24Guru covers what happens when those features meet real production environments, tight timelines, and ambiguous requirements.
If you are new to T24, surviving a migration, or trying to get sharper before an interview — this is built for you.

Production support, payment flows, incident diagnosis, and the things that trip every new TPH team up.
Migration
What changes, what breaks, what to test, and how to avoid the blind spots that derail most upgrades.
COB
Batch failures, restart procedures, job sequencing, and how to stay calm when COB does not complete.
Integration
How T24 talks to the outside world — OFS, SWIFT, MQ, file interfaces, and event-driven architecture.
Production support
Record locking, batch monitoring, escalation checklists, and the first 30 days after a go-live.
Industry
Interview preparation, the MT-to-MX migration, the Temenos rebrand, and how the industry is evolving.
Free checklist
A practical readiness sheet for teams that want to spot migration risk early, before it turns into expensive rework or a noisy go-live week.
What you get
No drip sequence. Just the checklist.

No. The content is designed for anyone working in T24 environments — from newcomers building foundational knowledge to seasoned professionals dealing with complex production issues, migrations, and architectural decisions.
Consistently, but without a fixed schedule. Quality comes before volume — one article that solves a real problem is worth more than five thin ones. Subscribers get notified when something useful lands.
No. Everything published is based on general T24 knowledge and professional experience — nothing proprietary, employer-specific, or identifiable. The goal is to share what helps, not what violates trust.
Absolutely. T24Guru is built around the questions that come up in real T24 environments. If there is something you would like covered, reach out — the best articles often start with a reader's question.
