   Migrating data from RocketMQ 4.x to 5.x:
   1. **Messages in transit:** Use RocketMQ Connect with a 4.x Source Connector and 5.x Sink Connector to bridge the two clusters
   2. **Consumer offsets:** Use the `exportOffsets` / `importOffsets` admin tools
   3. **Topic/Group metadata:** Recreate topics and consumer groups in the 5.x cluster
   
   For a zero-downtime migration, run both clusters in parallel and gradually shift producers/consumers to 5.x.
