Modernization

Retire the old system without risking your data

Rebuild or replace legacy software with a verified migration plan and a safe cutover.

What problem does this solve?

Old systems hold the business hostage when they cannot be changed safely. The data has to move with a plan, not a leap of faith.

How does Zygrix approach it?

Assess, plan, migrate a pilot slice, validate, cut over, then support.

What is the process?

Assess, plan, migrate a pilot slice, validate, cut over, support.

Where is this used?

  • Database moves between SQL Server, PostgreSQL, MongoDB and cloud services
  • Phased cutovers that cannot accept long downtime

Custom software vs off-the-shelf: when each fits

Choose off-the-shelf software when the process is standard. Choose custom software when packaged tools force the business to adapt to the software instead of the other way around.

How to rescue a vibe-coded or AI-generated app

A vibe-coded or AI-generated app is rescued by auditing what actually runs, fixing the unsafe parts and adding tests before new features. A full rewrite is only right when the current code cannot be made safe to change.

Questions

Answers people ask before they start.

Will we lose data during migration?

The plan includes mapping, cleansing, validation, a pilot slice and rollback. We do not cut over on a guess.

Can the old system keep running during the move?

Yes. Parallel running and a planned cutover are how we avoid a long outage.

Do you only rebuild, or can you improve the current system?

Both. Sometimes a phased replacement is right. Sometimes improving what you have is enough.
