Own case

SISCON ERP migration: 15 weeks, 0 days of downtime

We left GeneXus with our own management system, module by module and without stopping operations.

Context

SISCON ran its internal management system on GeneXus. It is the system the company itself is managed with.

Challenge

Leave GeneXus without stopping operations and keep the data with its identifiers.

Solution

We migrated module by module with route-based cutover: a single entry point splits traffic between the legacy and the new system. Every change was integrated with review and verified with automated tests.
