This Cumulative Update includes schema and AD changes, so make sure you runPrepareSchema / PrepareAD. After updating, the schema version will be ….
Note that Cumulative Updates can be installed directly, i.e. no need to install RTM or Service Packs prior to installing Cumulative Updates. Note that once installed, you can’t uninstall a Cumulative Update nor any of the installed Exchange server roles. The order of upgrading servers is irrelevant, unlike with previous generations of Exchange.
Finally, and I can’t emphasize this enough: For any Hotfix, Rollup, Service Pack or Cumulative Update, I’d recommend to thoroughly test this in a test and acceptance environment first, prior to implementing it in production. When you lack such facilities, hold out a week or two and monitor the comments on the release article or TechNet forum for any issues.

We would like to call your attention to a couple of items in particular about the Cumulative Update 5 release:
For the latest information and product announcements please read What’s New in Exchange Server 2013, Release Notes and product documentation available on TechNet.
Cumulative Update 5 includes Exchange related updates to Active Directory schema and configuration. For information on extending schema and configuring the active directory please review the appropriate TechNet documentation. Also, to prevent installation issues you should ensure that the Windows PowerShell Script Execution Policy is set to “Unrestricted” on the server being upgraded or installed. To verify the policy settings, run the Get-ExecutionPolicy cmdlet from PowerShell on the machine being upgraded. If the policies are NOT set to Unrestricted you should use the resolution steps in KB981474 to adjust the settings.
Reminder: Customers in hybrid deployments where Exchange is deployed in-house and in the cloud, or who are using Exchange Online Archiving with their in-house Exchange deployment are required to maintain currency on Cumulative Update releases.
