Which Redis and Valkey versions does Magento 2.4.9 support?
Every Magento 2.4.9 release we tested installs on Redis 5.0.14, 6.0.20, 6.2.22, 7.0.15, 7.2, 8.0.6 and 8.6.3, and Valkey 8 and 9.
Last run 1 October 2026. Each run is our baseline stack for the release, picked from Adobe's system requirements, with only the cache swapped, installed in Docker, compiled and put through storefront, checkout and admin browser tests.
