Migration without downtime
Modernization for Legacy Platforms
Modernizing a legacy platform means moving to a supported stack without breaking the business that runs on the old one. The hard part is never the new system. It is keeping the legacy system safe and available while the migration takes longer than planned.
Jestr keeps a live, isolated replica of the legacy platform: a clean reference for the rebuild, a fallback if the cutover fails, and a way to keep an end-of-life system running without exposing it. Pick your platform below.
