Exchange 2013 CU10 Released

Exchange 2013 CU10 has been released to the Microsoft download centre!  Exchange 2013 has a different servicing strategy than Exchange 2007/2010 and utilises Cumulative Updates (CUs) rather than the Rollup Updates (RU/UR) which were used previously.    CUs are a complete installation of Exchange 2013 and can be used to install a fresh server or to update a previously installed one.  Exchange 2013 SP1 was in effect CU4, and CU10 is the sixth post SP1 release.

Exchange 2013 CU10 Download

This is build 15.00.1130.007 of Exchange 2013 and the update is helpfully named Exchange2013-x64-cu10.exe.  Which is a great improvement over the initial CUs that all had the same file name!  Details for the release are contained in KB3078678.

Whether or not your AD Schema needs to be updated depends upon your initial Exchange 2013 version.  This will dictate if the AD Schema needs to be modified.  Check the values as noted in this post.   CU10 does not contain additional AD Schema changes, but does contain additional RBAC definitions. 

For those looking at deploying Exchange 2016, CU10 will be important.  Cumulative Update 10 is the minimum version of Exchange Server 2013 which will co-exist with Exchange Server 2016.

Some Items For Consideration

As with previous CUs, CU10 follows the new servicing paradigm which was previously discussed on the blog.  The CU10 package can be used to perform a new installation, or to upgrade an existing Exchange Server 2013 installation to CU10.  You do not need to install Cumulative Update 1 or 2 for Exchange Server 2013 when you are installing CU10.  Cumulative Updates are well, cumulative.  What else can I say…

  • After you install this cumulative update package, you cannot uninstall the cumulative update package to revert to an earlier version of Exchange 2013. If you uninstall this cumulative update package, Exchange 2013 is removed from the server.

  • Ensure that you consult with all 3rd party vendors which exist as part of your messaging environment.  This includes archive, mobility and management services.

  • Ensure that you do not forget to install this update on management servers, jump servers/workstations and application servers where the management tools were installed for an application.  FIM and 3rd party user provisioning solutions are examples of the latter. 

  • Disable file system antivirus prior to installing.

  • Once server has been restarted, re-enable file system antivirus.

  • Note that customised configuration files are overwritten on installation.  Make sure you have any changes fully documented!

  • CU10 may contain AD Schema updates for your organisation – please test and plan accordingly!  Whether or not your AD Schema needs to be updated depends upon your initial Exchange 2013 version.  This will dictate if the AD Schema needs to be modified.  Check the values as noted in this post

Please enjoy the update responsibly!

What do I mean by that?  Well, you need to ensure that you are fully informed about the caveats with the CU  and are aware of all of the changes that it will make within your environment.  Additionally you will need to test the CU your lab which is representative of your production environment.

Cheers,
