Hello,
I'm currently migrating Exchange 2010 SP3 (with Rollup Update 11) to Exchange 2013 CU11. The Exchange 2013 CU11 Setup completed without any errors. I'm attempting to run the "Set-ClientAccessServer -Identity EX2013 -AutoDiscoverServiceInternalURI https://autodiscover.myexternaldomain.com/Autodiscover/Autodiscover.xml" from the Exchange 2013 Management Shell on the Exchange 2013 Server, and I'm receiving the following error:
You can't make this change because 'CN=EX2013,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=myinternaldomain,DC=local' is read-only to the current version of Exchange.

Any ideas?
