Redis downgrade

[lsoica]

Assuming a Redis Cluster managed by the operator was upgraded from Version A to Version B. However, due to various reasons, this upgrade now needs to be rolled back. Given that the operator is subject to Redis's downgrade limitations (such as incompatible RDB versions, which can make downgrading impossible), what would be the advised method to revert to Version A?

Can the operator recognize that the target version is an older, incompatible version and, based on this information, clear the persistent volumes to allow a fresh start for the Redis process followed by loading a previously saved and compatible snapshot?
