Hi Guys,
My current version is "Microsoft Exchange Server 2013 RTM" and I would like to upgrade it to CU1. But I could see that this is a major upgrade and it would cause some AD permission changes and schema update. I also have an RD server and also a SharePoint server connected to the same AD. So, I'm a bit hesitant to do the upgrade an I fear that the permission changes would cause access problems to the users in RD server and SharePoint server.
Could someone shed some light on this? Also, would there be any issues with this CU1 update? Could someone share the steps to perform this upgrade? The Mailserver and ClientAccess roles are configured on the same machine.
