Summary

Sonata Software partnered with a leading Indian infrastructure conglomerate to migrate its end-of-life on-premises datacenter to Microsoft Azure. Using a phased lift-and-shift approach, Sonata moved ~100 Windows and SQL servers, including critical ERP systems, analytics platforms and collaboration tools.
