Many companies still run on software developed in the 90s (Legacy), which is slow, ugly, and doesn't work on mobile. **Jestor** is the fast track to **Modernization**, allowing you to recreate these systems on a modern web platform in weeks, not years.

### **The Legacy Software Risk**

The old system runs on a dusty local server. If it crashes, the company stops. Jestor runs in the cloud (AWS), with automatic backup and top-tier security.

### **Usability the team loves**

Old systems require complex training. Jestor is intuitive (looks like a mobile app). New employees learn to use it in 15 minutes, increasing immediate productivity.

### **Frequently Asked Questions (FAQ)**

**Can I migrate old data?** Usually yes. We export the old database to CSV and import into Jestor to keep history.

**Is it expensive to maintain?** Legacy software has hidden server and IT maintenance costs. Jestor is SaaS (subscription), with predictable costs and no infrastructure spend.

**Can I customize it like the old one?** Yes. Since Jestor is a builder, you can recreate the exact fields and rules your company is already used to using.

### **Conclusion**

With **Jestor**, you bring your company into the 21st century.
