Keep CQL, Simplify Apps, Cut Costs:
From DataStax to YugabyteDB Migration with HexaRocket

How to Keep Cassandra-Scale, Gain ACID, and Avoid Vendor
Lock-In

IBM’s acquisition of DataStax is complete, and the Stargate APIs have been discontinued. The roadmap teams built on no longer belong to the company they initially chose.

For most teams, the question isn’t whether they should modernize, but rather if the IBM acquisition will require them to rewrite years of CQL-based applications and data models.

Many enterprises are now reconsidering their database options and taking the opportunity to explore open-source alternatives that provide native CQL compatibility. They need a database that delivers the relational guarantees, distributed scale, and multi-region resilience modern applications require, without abandoning the Cassandra work already built.

Why Watch?

In this webinar, Avi Vallarapu, CEO at HexaCluster, and Alan Caldera, Distinguished Engineer at Yugabyte, walk through the engineering steps needed to migrate from DataStax Cassandra to YugabyteDB and demonstrate a practical path forward using HexaRocket.

What You'll Learn

  • What IBM’s acquisition means for DataStax and Astra DB customers, and why you should consider your options before your next renewal

  • Why Cassandra’s consistency model creates compounding engineering costs as applications scale, and how a relational model at distributed scale avoids this

  • How to migrate without a rewrite: CQL compatibility, schema conversion, data migration, and CDC-based replication in YugabyteDB

  • A live demo of HexaRocket working through an end-to-end migration from DataStax Cassandra

  • Interactive Q&A on migration planning, compatibility checks, and what the process realistically involves

Register now and join us at 12:00 PM ET on July 28, 2026. Can’t make it to the live session? Sign up today, and we’ll send you the on-demand recording.
