Modernizing old systems
Software modernization for the system nobody dares touch.
Aatvi replaces an old system one part at a time. Each new part is checked against the old one before it takes over, so the business keeps running.
For the founder or team whose business runs on software that works, but that nobody wants to change. It starts with an assessment of the old system and a staged plan.
Pooja Kumari and Niraj Kumar hold the first conversation. It costs nothing and commits you to nothing. We reply within one working day.
What you buy first
An assessment of the old system, and a staged plan.
Before anything moves, we look at what you have and agree the order. The assessment and the plan are the first paid step; the move itself is agreed separately.
What it includes
- An assessment of the old system: what it holds, what depends on what, and the rules that only live in its code.
- A staged plan: which part moves first, how each new part is checked against the old one, and how to go back if one does not match.
What it leaves out
- A rewrite that replaces everything in one release.
- A new coat of paint over a system nobody understands.
What it leads to
- Moving the system one part at a time, in the order you agreed, while the business keeps running.
- You decide after the plan whether Aatvi does the move, or your own team does.
How a part moves
One part, then the next, checked each time.

Look at the old system
We read it first: its data, its dependencies, what runs at night. The old system keeps serving the business throughout.
- 2
Agree the order
The plan names the parts and the order they move in. Nothing starts before you have agreed it.
- 3
Move one, compare it
Each new part is compared with the old one before it takes over. If it differs, it stays on the old system until it matches.

Hand over, then the next
When a part matches, it takes over. Then the next part. That is the board above, in the order of your system.
Who it is for
Software that works, and that nobody wants to change.
It suits
- A founder or a small team whose business runs on an older application, and the person who built it has gone.
- A system with no tests and no documents, that still has to run tonight.
- A team that wants the old system replaced without a stop in the business.
It does not suit
- A request to replace the whole system in one release. We do not take that on.
- A change of appearance only, with the system underneath left as it is.
Aatvi takes on an application whoever built it, with or without AI tools.
Price and start
How the price is set, and when you learn it.
A service like this cannot be priced from a table: every system is different. So we price it after we have talked.
The first conversation costs nothing and commits you to nothing. Scope, fee and schedule are agreed with you in writing before any paid work starts.
We agree access before we see any code.
Who does the work
People you can look up.

Questions
What people ask first.
Can we modernize without rewriting the whole system?
Yes. That is the approach. We replace the system one part at a time, and the old one keeps running until each new part has been checked against it and matches.
How do you keep the business running while parts move?
The old system stays in service. A new part takes over only after it has been compared with the old one. If the comparison shows a difference, the part stays on the old system until it matches, and the plan says how to go back.
What do we get first, and what does it lead to?
An assessment of the old system and a staged plan. The move itself is agreed separately, after the plan, and you decide whether Aatvi or your own team does it.
How is it priced, and when do we learn the price?
After a first conversation that costs nothing and commits you to nothing. Scope, fee and schedule are agreed with you in writing before any paid work starts.
Does the old system have to be one that was built a long time ago?
No. Aatvi takes on an application whoever built it, with or without AI tools, including one whose developer has gone.
