The following error messages are considered high risk breaking change, so they will be controlled by special compatibility configuration, thus they are not in scope in this issue:

"-MISCONF Redis is configured to save RDB snapshots (...)"
"-LOADING Redis is loading the dataset in memory"
"-BUSY Redis is busy running a script (...)"

All other error replies containing "Redis" can be changed, either by removing "Redis" or changing it to "Valkey", "the server" or something else, depending on context.
