Informix Professional Services
Upgrade, migrate, or modernise your Informix estate with a UK specialist team. One partner for assessment, planning, and delivery.
Challenges we solve
Changing a database that runs the business is daunting. These are the worries we are built to handle.
Support deadlines are closing in
IBM withdrew support for Informix 12.10 on 30 April 2026. Running an unsupported release is a growing risk, and you need a clear plan to address it.
Upgrades feel risky
A botched upgrade can mean downtime, data issues, and frustrated users. You need rehearsal, rollback, and a team that has done this many times before.
You are weighing your options
Stay on Informix, move to a newer release, or replatform entirely? Each path has trade-offs, and the wrong call is expensive to unwind.
In-house capacity is stretched
Your team is busy keeping the lights on. A migration project needs focus and specialist skills you may not have spare in the day job.
What are Informix Professional Services?
Informix Professional Services is a single, joined-up service for changing your Informix estate safely. Whether you need a version upgrade, a migration to the cloud, or a full modernisation programme, we plan it and deliver it with you, end to end.
We start with assessment, not assumptions. We look at your current estate, your applications, your data, and your constraints, then recommend the path that carries the least risk for the outcome you want. Sometimes that is an in-place upgrade. Sometimes it is a move to a supported Informix release or a different platform. We help you choose with your eyes open.
Delivery follows a tested pattern: assess, design, convert, move the data, rehearse, then cut over with confidence. We tune SQL, storage, and workloads as we go, and we keep you informed at every stage, so there are no surprises on cutover weekend.

Why Claranet?
A UK team that has delivered database upgrades and migrations across mixed estates for years.
Everything in one service
Upgrades, migrations, and modernisation are rarely tidy, separate jobs. We bring them together under one plan and one team.
Discovery & assessment
A full inventory and health baseline of your estate before anything changes.
Upgrade
In-place upgrades to a supported Informix release, planned and rehearsed.
Migration
Moving Informix onto new infrastructure or the cloud with minimal downtime.
Replatforming
Where it is right for you, modernising onto a different database platform.
Data movement
Initial loads, replication, and a validated, controlled cutover.
Tuning & optimisation
SQL, storage, and workload tuning to get the best from the target.
Technical capabilities
The technical work that turns a risky change into a controlled, well-rehearsed delivery.
Estate assessment
We baseline performance, capacity, and risk, and map application dependencies before any change. You get a clear starting point and a costed plan.
Upgrade planning
We plan direct upgrade paths to current, supported Informix releases, with full rehearsal and a tested rollback so you are never cornered.
Cloud migration
We move Informix to the cloud or to new infrastructure, designing for availability and performance rather than a simple lift-and-shift.
Schema and code conversion
Where you replatform, we handle schema conversion, code remediation, and validation, so your applications behave as expected on the new platform.
Low-downtime cutover
Replication, delta sync, and controlled cutover windows keep disruption to a minimum, with a clear go and no-go decision point.
Validation and UAT
We check row counts, checksums, replication lag, and query plans before you go live, and run user acceptance testing so the business signs off with confidence.
How we deliver
Professional services are scoped per project, but the shape of an engagement is consistent. Indicative stages below.
| Stage | What happens |
|---|---|
| Discovery & assessment | Inventory, health baseline, risk and options review |
| Design | Target architecture, security, backup, and HA design |
| Conversion | Schema and code analysis and remediation |
| Data movement | Initial load, rehearsal cycles, and validation |
| Release | Cutover, final sync, and hypercare |
Timescales depend on the size and complexity of your estate and the path you choose. We give you a costed plan with milestones after assessment.
