In MongoDB upgrade 6.0 on Sharded Cluster, do we need to restart mongos service before config servers upgrade?

Hello,

I am starting with 6.0 upgrade process on sharded cluster, but official document says that we need to restart mongos services one by one in sequence before upgrading config servers. Is this required? aren’t we going to restart them when we are upgrading mongos package? Any importance of this step? We have 40+ servers in production.

2nd step from this document - Upgrade a Sharded Cluster to 6.0 - Database Manual v8.0 - MongoDB Docs
