Hi team,

I think "Rename a Replica Set" documentation page could be clarified in a couple ways:

1. Steps 2(a) and 2(b) should be switched – 2(a) says to update the replica set name, but then 2(b) says to launch `mongod` without replication enabled.

2. The page should mention that if the customer is using Ops Manager, they will need to "unmanage" the replica set from the Ops Manager UI before shutting down the replica set members. The process looks sort of like this:

1. Unmanage the replica set from Ops Manager. On Ops Manager UI, Deployment > Processes > [...] menu > Remove from Ops Manager > Completely Remove Ops Manager).
2. Before shutting down the members, run `ps -ef | grep mongo` and copy the command line/configuration file options for `mongod` to start the members up again later for reference. Be sure to use the same OS user (normally mongod) to start them. E.g. something like: `sudo -u mongod /var/lib/mongodb-mms-automation/mongodb-linux-x86_64-4.4.4-ent/bin/mongod -f /data/mdb1/automation-mongod.conf` to start them manually.

Thanks for making the best docs on the whole internet,
Matt
