SQL Server is a relational database management system (RDBMS) developed by Microsoft. It stores and retrieves data as requested by other software applications, supporting structured query language (SQL) for managing and manipulating data. It offers features for data storage, retrieval, and analysis, making it a powerful solution for managing databases.

You’ll have to migrate your data model, the data itself, and make changes to the application (the business function).  
There are a few ways to do this, offline migration (also called Cold Migration) or zero downtime migration (also called Hot Migration or online migration).  
You can learn more in the [Migrating to ScyllaDB lesson](https://university.scylladb.com/courses/scylla-operations/lessons/migrating-to-scylla/) on ScyllaDB University. If you have specific questions feel free to ask here.
