The IT landscape has evolved dramatically over the past decade, with cloud-native architectures, advanced analytics, and AI reshaping the way businesses use data. However, legacy platforms like Sybase Adaptive Server Enterprise (Sybase ASE) struggle to meet modern requirements such as horizontal scalability, real-time insights, and support for AI workloads. As SAP announces the end of life of this platform, organizations relying on it face a critical decision. Document databases like MongoDB have emerged as transformative alternatives, offering unmatched flexibility and speed. To address the complexities of Sybase-to-MongoDB modernization, PeerAI, a platform from PeerIslands, was developed to simplify and accelerate the migration process using generative AI (gen AI) and expert developers' knowledge. By automating critical steps in the migration process, PeerAI delivers faster timelines, cost savings, reduced risk, and future-ready architecture, helping organizations navigate this transformation efficiently and confidently.
