Description of Cumulative Update 2 for Exchange Server 2013

Unlike previous versions, cumulative updates do not use the rollup infrastructure; cumulative updates are actually full builds of the product, meaning that when you want to deploy a new server, you simply use the latest cumulative update build available and do not necessarily need to apply additional Exchange Server updates.

Prior to upgrading or deploying the new build onto a server, you will need to update Active Directory. For those of you with a diverse Active Directory permissions model you will want to perform the following steps:

1. Exchange 2013 RTM CU2 includes schema changes. Therefore, you will need to execute setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms.
2. Exchange 2013 RTM CU2 includes enterprise Active Directory changes (e.g., RBAC roles have been updated to support new cmdlets and/or properties). Therefore, you will need to execute setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms.
