About the Author

Chetan Nihalani is an SAP technology specialist whose career has focused on the administration, migration, and modernization of enterprise SAP landscapes. With over eight years of hands-on experience, he currently works as an SAP Technology Specialist, concentrating on system upgrades and conversions for organizations transitioning to modern SAP platforms.

His professional journey began in application development and support roles, where he built a strong foundation in SAP system operations and search technologies such as TREX. Progressing through consulting positions of increasing responsibility, he moved into technical specialization areas that now define his expertise, including SAP Basis administration and complex conversion projects.

Much of his current work centers on SAP S/4HANA conversion and system upgrades, including the use of Database Migration Option and the Software Update Manager with its zero-downtime capabilities. His technical range extends across multiple database platforms, including HANA, Oracle, MaxDB, and SQL Server, and spans both Linux and Windows operating systems. He also brings experience deploying and managing SAP workloads on AWS and Azure cloud infrastructure.

His credentials reflect a deliberate investment in both technical depth and architectural breadth. He holds SAP certifications as a Technology Specialist for S/4HANA Conversion and System Upgrade, an Implementation Consultant for S/4HANA Cloud Private Edition, and a Solution Architect for SAP BTP, along with associate certifications in enterprise architecture and business transformation. He earned a Bachelor of Engineering in Computer Engineering.

This blend of operational experience and architectural understanding informs the way Chetan Nihalani approaches his writing. Instead of treating upgrades and conversions as abstract exercises, he explains the practical considerations that determine whether a project succeeds, from downtime planning to database and infrastructure choices. His articles are intended to help administrators, consultants, and architects make informed decisions and carry out SAP transformations with greater confidence.
