What changes when it is government & public sector
The riskiest asset in a legacy migration is the two people who understand the old system. Knowledge capture comes first, before anyone writes new code.
In government & public sector, procurement, data sovereignty and accessibility obligations shape the architecture before anything else. That single fact reshapes how legacy system modernisation has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.
The workload we are most often asked to take on first is multilingual service delivery, usually integrated against legacy record systems. We start from the constraint, not the capability, what the system must never do, who signs off, and what happens when it is wrong.
Multi-model by default, so a provider outage is a routing decision rather than an incident. We hand over with runbooks, tests and a team that knows how it works, not a dependency.

Questions from this sector
Can AI systems be procured under GeM?
Yes, and we structure deliverables to fit standard procurement categories and evaluation criteria.
Does it work in regional languages?
It has to. Public services in India are multilingual by obligation, and we build for that rather than adding translation later.
Can we migrate without downtime?
Usually yes, with incremental migration and parallel running. Some database cutovers need a short window, which we plan and rehearse rather than improvise.
What if nobody understands the old system?
That is common and we treat it as the first work package, behaviour is reconstructed from code, logs and observed production traffic before anything is replaced.
How long does it take?
It depends entirely on scope, but incremental migration means value lands continuously rather than at the end of a multi-year programme.
