Why modernize with CockroachDB?
Agility and flexibility
Build on a cloud-native infrastructure to quickly adapt to market changes and customer requests
Time and money
Reduce operational, capital, and MIPS expenses associated with mainframe hardware and specialized personnel
Scale and resilience
Achieve automated, horizontal scale (up and down) with enhanced disaster recovery capabilities
Global scale, access, and efficiency of the cloud
CockroachDB not only supports modern application development in the cloud, but also provides feature parity with legacy databases in mainframes, making it an ideal target database for executing critical mainframe workloads.

Distributed SQLProven migration strategies
Data replication
Scale-out reads for digital channels and online workloads. Unlock operational data (analytics, GenAI) and reduce millions of instructions per second (MIPS) costs
Re-platform
Modernize with minimal application changes (via a lift-and-shift strategy) to create a faster time-to-value and reduce overall spend
Re-factor
Detach from legacy Db2, IMS, and VSAM to reduce infrastructure and code-maintance costs and eliminate the need for specialized personnel
Work with our strategic partners to streamline the migration process
