 Description   

What is the intent of the following sentence in the upgrade notes for v2.4?

If you complete the meta-data upgrade, you can have a mixed cluster that has both 2.2 and 2.4 mongod and mongos instances, if needed. However, do not create 2dsphere or text indexes in a cluster that has 2.2 components.

It's not obviously consistent with the instructions that the cluster should be upgraded in a particular order (mongos, config servers, shard members).

If the note is only supposed to be about what's safe to downgrade (it's physically below a heading about downgrading), and is saying that the cluster may be downgraded in any order, or something to that effect, please clarify.

Customer cited the offending line in defense of their having upgraded shards first, before mongos and config servers.
