      A failed attempt to downgrade a sharded cluster from FCV 8.0 to 7.0 can leave the version in a downgrading state.

      In this situation, the moveCollection command fails because the underlying resharding functionality depends on features that are only available starting from FCV 8.0.

      The current error message is:

      MongoServerError[InvalidOptions]: Resharding improvements is not enabled, reject shardDistribution parameter

      However, this error message is difficult to interpret unless you are an engineer familiar with the feature. A clearer and more helpful error message would be:

      This command requires FCV 8.0 or higher.
