We have 2 primaries and 10 satellites.

One satellite is not used anymore and needs to be removed.
That satellite has content / authentication / imaging role configured.

I found this documentation :

What is the best way to remove it from our zone? Via command line or via the ZCC?
What worked the best for you?

I also saw that this satellite is configured to the second primary as parent.
If I do this command line , do I have to specify the address second primary for the removal ?

Do both ways remove the roles?

The last thing to do is remove the agent, am I correct?
