Zero Downtime, Zero Client Code Changes: Migrating from Apache Kafka® to Confluent Cloud (Deep Dive)

More: https://developer.confluent.io/ | Confluent's KCP moves your clients over with no code changes and a cutover window under 30 seconds. Migrating Kafka clients to Confluent Cloud usually means rewriting client configs, coordinating a big-bang cutover across teams, and hoping the rollback plan works if something breaks. It doesn't have to. KCP, Confluent's open-source CLI, migrates both your Kafka data and to Confluent Cloud with zero code changes and a cutover window under 30 seconds. Client apps keep their existing code and credentials: only a bootstrap URL is updated. Cluster Linking replicates topic data and consumer offsets, so consumers pick up in Confluent Cloud exactly where they left off, while producers simply buffer for a few seconds during cutover. KCP groups related topics and clients into "migration groups," so each team migrates on its own schedule instead of a big-bang cutover, and Confluent Cloud Gateway translates credentials behind the scenes so clients keep authenticating the way they always have.
