Valkey as a Redis replacement: a real migration with Valkey 8.1
Valkey 8.1, released on March 31, is protocol and command compatible with Redis 7.x, so most existing clients connect without code changes. Swapping Valkey in for Redis is a realistic move once you plan the cutover: dump and restore is the simplest path, while zero downtime needs asymmetric replication. We moved our first production cluster two weeks ago.
