Questions we hear often.
Do we need to rewrite everything?
Rarely. Most modernizations replace the riskiest parts first and keep what still works.
Will there be downtime?
We plan cut-overs in small steps, usually outside business hours, with a rollback plan for each.
Can you work with old technologies like classic PHP or .NET Framework?
Yes. Understanding the existing system is the first step of every modernization.
How long does it take?
It depends on the size of the system. The audit gives you a phased plan with timelines and costs.
