Cloud & security
Modernise legacy systems without stopping the business.
Big-bang rewrites are where projects go to die. We modernise step by step: the old system keeps running while new parts replace it piece by piece, each one tested in production before the next begins.
- Modernisation & cloud migration
- Phased, from 6 weeks
When to call us
Sound familiar?
- 01
Your core system runs on unsupported frameworks or end-of-life servers.
- 02
Simple changes take months because nobody dares touch the code.
- 03
You need to leave a data centre or reduce hosting costs.
How Tulmira handles it
Our approach, step by step
- 1
Audit
A short paid review of architecture, code health, security and dependencies, with a clear keep, fix or replace verdict.
- 2
Plan the route
A phased roadmap where every step delivers value on its own and can be paused safely.
- 3
Strangle, don't rewrite
New services take over one capability at a time behind the existing interfaces, with traffic shifted gradually.
- 4
Migrate and retire
Data migrated with reconciliation checks, then old components switched off once the new ones have proven themselves.
Our standards
Non-negotiable practices
- No big-bang cut-overs: every step reversible
- Characterisation tests written before legacy code is changed
- Data migrations rehearsed and reconciled record by record
- Business continuity agreed before each phase
- Framework upgrades kept on supported versions
- Knowledge captured in documentation as we go
What you get
- Technical audit report and modernisation roadmap
- Migrated services and data in the target platform
- Regression test suite protecting existing behaviour
- Decommissioning plan for legacy infrastructure
Tools we use for this
- Angular
- Spring Boot
- Java
- Kubernetes
- Terraform
- AWS
- Azure
It is phased, so you see results from the first phase, typically within six to eight weeks. The full journey depends on the size of the system.
