Exchange 2013, do I need cas array configuration?

Question

Hello,
I have a setup of 2 mailbox servers and 2 cas servers (cas1.demo.local, cas2.demo.local).
Created dns-round-robin for the two cas servers.
Created host A record for cas.demo.local
Setup internal url's  to point cas.demo.local
I'm planing to test loadbalancer for the cas-services.
Do I need to setup CAS-Array?
Im getting error from the "New-ClientAccessArray" cmdlet
[PS] C:\Windows\system32>New-ClientAccessArray
New-ClientAccessArray : The term 'New-ClientAccessArray' is not recognized as the name of a cmdlet, function, script fi
le, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and

As I understood it, the individual servers still use their individual names ... you still need to configure exchange to use only one name ... the difference is that it is a lot simpler now. with exchange 2010 you had to use
new-clientaccessarray -name -fqdn -siteand afterwards you had to configure the mailboxdatabases to use the array with
set-mailboxdatabase database -rpclientaccessserver name of the array
then with the advent of exchange 2013 u just use
get-outlookanywhere |set-outlookanywherer -internalname -externalname
it is the -internalname with set-outlookanywhere that is new. In exchange 2010 you only could configure the externalname with set-outlook-anywhere and therefore you had to use new-clienteaccessarray and set-mailboxdatabase
