Hi there,
https://support.microsoft.com/en-us/kb/3078678
I’m nervous about upgrading to CU10 as I don’t have a test environment to try it in beforehand.
Already have downloaded Exchange2013-x64-cu10.exe (1.6GB) and I’m guessing that I need to download Exchange Server 2013 CU10 UM Language Packs from:![Exchange 2013 cu1 download iso version Exchange 2013 cu1 download iso version](/uploads/1/2/5/7/125731047/211193547.png)
http://www.microsoft.com/en-us/download/details.aspx?id=49045
Do I need to upgrade the Active Directory (Schema, Configuration and Domain) to the CU10 level by using the following commands? Or, CU10 upgrade will do it for me anyway?
Setup.exe /prepareSchema /IAcceptExchangeServerLicenseTerms
Setup.exe /prepareAD /IAcceptExchangeServerLicenseTerms
Setup.exe /prepareDomain /IAcceptExchangeServerLicenseTerms
Would you recommend to upgrade Exchange 2013 server is to use the unattended setup, or GUI setup is quite OK to run too?
Setup.exe /mode:upgrade /IAcceptExchangeServerLicenseTerms
What if (I hope not) CU10 upgrade will fail for some unexpected reason and I need to recover everything back (how it was before the CU10 upgrade)?! Our Ex2013 is virtual (hyper-v) , so I guess I could recover VM from the backup, but will I need to downgrade Active Directory (Schema, Configuration and Domain) to the previous version?
Any advice and help highly appreciated. Thanks. -->
Microsoft has released Cumulative Update 1 (CU1) for Exchange Server 2013 RTM. This is a significant update for two reasons. It is the first release of a CU under Microsoft's new servicing model for Exchange Server 2013.And it is the minimum version of Exchange 2013 required for on-premises co-existence with Exchange 2007 (SP3 UR10) and Exchange 2010 (SP3). The download is an impressive 1.3Gbyte in size because Microsoft switched to build-to-build upgrades with the same experience as service packs. More information @ Announcement on Exchange Team Blog. Technet documentation (expected to be available on April 3rd) KB2816900 – Description of Cumulative Update 1 for Exchange Server 2013.
We need to upgrade our Exchange 2013 SP1 server with the Cumulative Update 10 (CU10). From what I can see, we don’t need to install CU1 or a later cumulative update for Exchange Server 2013 when you install Cumulative Update 10. Also, there are no way to uninstall CU10 from the Exchange 2013. If you uninstall this cumulative update package, Exchange Server 2013 is removed from the server.https://support.microsoft.com/en-us/kb/3078678

Applies to: Exchange Server 2013
If you have Microsoft Exchange Server 2013 installed, you can upgrade it to the latest Exchange 2013 cumulative update or service pack. You can use the Exchange 2013 Setup wizard to upgrade your current version of Exchange 2013. For more information about the latest Exchange 2013 cumulative update or service pack, see Updates for Exchange 2013. To learn more about Exchange 2013, see What's new in Exchange 2013.
Warning
After you upgrade Exchange 2013 to a newer cumulative update or service pack, you can't uninstall the new version to revert to the previous version. If you uninstall the new version, you remove Exchange from the server.
What do you need to know before you begin?
- Estimated time to complete: 60 minutes
- Make sure you read the release notes before you install Exchange 2013. For more information, see Release notes for Exchange 2013.
- Make sure that any server on which you plan to install the cumulative update or service pack meets the system requirements and prerequisites. For more information, see Exchange 2013 system requirements and Exchange 2013 prerequisites.WarningAny customized per-server settings you make in Exchange XML application configuration files, for example, web.config files on Client Access servers or the EdgeTransport.exe.config file on Mailbox servers, will be overwritten when you install an Exchange Cumulative Update (CU). Make sure that you save this information so you can easily re-configure your server after the install. You must re-configure these settings after you install an Exchange CU.
- After you install a cumulative update or service pack, you must restart the computer so that changes can be made to the registry and operating system.
