Shard key change post sharding

Hi, I’ve been revising MongoDB sharding concepts at MongoDB university course. I want to correct my understanding of shard key concept mentioned in the documentation vs covered in the video.
As per new versions of MongoDB, shard key can be updated/refined post sharding. However course video says, it’s not possible. Same is the case of missing shard keys.
I assume that documentation is latest. So, requesting MongoDB university course team to kindly correct his.

Hi :wave: @neeraj,

Thanks for pointing this out. We know this is can be a bit confusing but be assured we will forward this feedback to the concerned team.

Please feel free to reach out for anything else as well.
