Migration from Cassandra v3 to Cassandra v4

Hello,

I am looking to migrate a Cassandra dabatase V3 (3.11) running in AWS EKS to version v4 in the same kubernetes cluster.

I am checking if there is a solution to migrate without downtime. I saw that a replication mechanism is available using additional seeds.

Will this feature also work if the current database version is v3 ?
